Frequently Asked Questions - MTT4W MATSUI

How do I install the dishwasher?

Place the dishwasher on a stable, level surface. Connect the water inlet hose to a cold water tap (3/4 inch) and route the drain hose into a sink drain or standpipe. Plug into a grounded outlet. Ensure the appliance is level by adjusting the feet.

Which detergent should I use?

Use a dishwasher detergent in powder, gel, or tablet form. For best results, use a detergent with rinse aid built-in or add rinse aid separately.

Why is my dishwasher not cleaning dishes properly?

Check that the spray arms can rotate freely and the filters are clean. Ensure dishes are not blocking the spray arms. Use the correct program and sufficient detergent. Hard water may require more detergent or a water softener.

What does the error code E5 mean?

Error code E5 indicates a water inlet issue. Check that the water tap is open, the inlet hose is not kinked, and the water pressure is sufficient. If the problem persists, the inlet valve may need replacement.

How do I clean the dishwasher?

Regularly clean the filters under running water. Wipe the door seal and spray arms with a damp cloth. Run a maintenance cycle with a dishwasher cleaner or vinegar once a month to descale.

Can I wash pots and pans?

Yes, but they should be placed face down on the lower rack. Avoid tall items that may block the upper spray arm. Use the Intensive program for heavily soiled cookware.

The dishwasher is making unusual noise. What should I do?

Check that nothing is loose inside, like a utensil falling onto the bottom. Ensure dishes are properly loaded. Loose objects can cause rattling. If the noise persists, inspect the motor or pump for issues.

How do I reset the dishwasher?

Press and hold the START button for 5 seconds to cancel a cycle and reset the control board. Alternatively, unplug the dishwasher for 2 minutes and then plug it back in.

What is the maximum dish size?

The upper rack holds glasses and cups up to 15 cm tall. The lower rack accommodates dinner plates up to 25 cm in diameter. Check the manual for exact dimensions.

How do I replace the spray arms?

Turn off the power and water. Remove the lower rack. Unscrew the spray arm nut counterclockwise. Lift off the old spray arm and replace with a new one. Tighten the nut securely.

Save These Instructions

WARNING

Instructions pertaining to a risk of fire, electric shock, or injury to persons.

Electrical Instructions:

An electrical supply of 220-240 volts AC only, 50Hz is required. Make sure that a suitable electrical supply socket is located close to where the dishwasher is to be placed. For your personal safety, the appliance must be earthed. The appliance is equipped with a power supply cord having a 3-pin grounding plug. To minimize possible shock hazards it must be plugged into a matching 3-pin grounding type electrical outlet. If the mains plug is unsuitable for the socket outlet in your home or is removed for any other reason, a new plug must be connected by a qualified person before use.

Installation Instructions

Remove All Packing Materials Carefully

1. The water inlet hose from the machine terminates in a 3/4 " female connector. The water supply should therefore terminate in a similar male connector and should have a stopcock close by in the pipe. It is recommended to connect the machine to hot water supply. Connect the straight connector of the inlet hose to the water supply securely. Connect the other end (bent connector) to the water inlet valve at the back of the dishwasher cabinet. Do not over-tighten to avoid damage to threads.

2. Prepare the drainage hose so that it has hooked end. Use the plastic U-bend fitting provided for this purpose. The end of this should be dropped into a drainage standpipe, the maximum height of which should be no more than 6" above the base of the dishwasher. To allow for an air gap around the end of the drain hose, the diameter of the standpipe should be at least 30 mm. Connect the other end of the drain hose (L shaped) to the drain port connection at the back of the dishwasher cabinet. Tighten the drain hose end on to the drain port using the metal clip included in the package.

1. If you so wish, you may connect the water inlet hose on to the kitchen sink tap. Connect the water supply hose to a threaded 3/4(inch) connector and make sure that it is fastened tightly in place.

1. If leaks are located, immediately shut the water supply and check the hose connections fully. Tighten connections if necessary.
2. If for any reason you are unable to stop the leak yourself please seek advice from a qualified plumber.
3. The minimum height clearance required to install your dishwasher on a countertop surface with overhead cupboards is 19" (48cm).
4. Make sure there is an electrical power supply within easy reach of the machine. The power cord is 200cm long.
5. The dishwasher must be installed on a 'solid' level surface.
6. To level the dishwasher, adjust the 4 level screws (feet) under the dishwasher.

Water Pressure

For best operating results, incoming water pressure should be between 0.03\~1Mpa. Incoming water supply for the dishwasher is controlled by a 'low water switch' application, so if household water supply should be disrupted dishwasher will stop.

For Best Results:

Your dishwasher cleans by spraying a mixture of hot clean water and detergent (under pressure) against the soiled surface of dishes. The water is pumped through a rotating spray arm, drained through a filter removing food and soiled particles and pumped back through the spray arm.

Soiled water is pumped out and replaced with clean water at the end of each cycle (the number of times depends on the cycle being used). For best cleaning results, the water temperature must be at least 55° C. To prevent dishwasher damage, the temperature of the incoming water supply should not exceed 70° C.

NOTE: Hard Water conditions will adversely affect wash ability performance of your dishwasher. Hard Water conditions will also contribute to "Lime" (white film substance) deposits and/or "Scaling" on the stainless steel surface of the dishwasher tub and "Heater Element" located in the sump underneath the removable filter screen. To assist in minimizing these conditions, it is recommended to periodically operate/rinse the inside of the dishwasher (empty) using 1 cup of white vinegar (at least once a week).

Disconnecting your Dishwasher

→ Close the water supply at the stopcock.
→ Disconnect the power supply cord.
→ Disconnect the inlet hose assembly from the water supply. When the dishwasher is not in use, place/store the hose on the hanger hose bracket located on the rear wall of the dishwasher cabinet.
→ Appliances that are to be discarded must be made unusable. Pull off the plug, remove cable and make the door lock and latch unusable

NOTE

Once you open the water supply line, (even if it is closed immediately thereafter) the water inlet hose will be pressurized.

WARNING

Do not let children disconnect the dishwasher. Close supervision of children is always important around appliances.

Loading your Dishwasher

The dishwasher is designed to receive a standard "4 piece" plate setting consisting of the following:

NOTE: for ease of loading/unloading large size dinner plates from the dish rack it may be necessary to (temporarily) remove the cutlery basket. When loading/unloading is complete, return the cutlery basket to its original position.

Preparing your Dishes for Washing

Scrape off all solid food particles from the dishes.

→ Remove excessive quantities of oil or grease.

→ Empty any liquids from glasses and cups.

→ NOTE: Dishes with dried-on foods are more difficult to wash and may not come clean in a normal wash cycle.

→ Arrange all items with recessed or curved sections on a slant to drain water away.

→ Cups, pots, glasses, etc should be placed upside down.

When loading items to be washed:

→ Locate sharp items so that they are not likely to damage the door seal.

→ Load sharp knives with the handles up to reduce the risk of cut-type injuries

→ Do not load plastic items unless they are marked "dishwasher safe" or the equivalent. For plastic items not so marked, check the manufacturer's recommendations.

→ Do not load glasses over the dish rack pins. Glasses loaded over dish rack pins are not properly supported and are likely to get damaged.

→ Items with wooden or bone handles and items joined together with glue are unsuitable as they cannot resist hot water.

→ Do not touch the heating element during or immediately after use.

→ Do not operate your dishwasher unless all enclosure panels are properly in place.

→ Do not tamper with controls.
→ Do not abuse, sit on, or stand on the open door or dish-rack of the dishwasher. The machine may topple over.
→ Protect cables and hoses from high temperatures.
→ To reduce the risk of injury, do not allow children to operate or play with the dishwasher.

Using the Right Detergent

The recess for the detergent

Use only detergent specifically made for use in dishwashers, as other types will cause over-sudding. If your detergent is old and/or lumpy, throw it away. Old detergent loses its washing power. Lumpy detergent won't dissolve.

Please put the detergent at the recess which is at the left of the inner door.

How much Detergent Should You Use

That depends if your water is 'hard' or 'soft'.

HARD WATER REQUIRES MORE DETERGENT TO GET DISHES CLEAN. SOFT WATER REQUIRES LESS DETERGENT TO GET DISHES CLEAN.

→ The recessed detergent area located on the inside door panel will hold approximately 12g of detergent. Follow the detergent manufacturer's guidelines.

How to use the 3 in 1 program

Your dishwasher has a 3 in 1 program which needs no salt and rinse aid but a 3 In1 tablet. And this dishwasher comes with a 3 in 1 tablet container as an accessory.

Note:

Only 3 in 1 program uses 3 in 1 tablet. If using 3 in 1 tablet in other programs, the appliance will not get a best performance.

1. Hang the 3 in 1 tablet container on the basket..
2. Put the 3 in 1 tablet into the container then start the 3 in 1 program.

The tablet container

Note:

When using a 3in1 tablet, you do not need to add any rinse aid into the dispenser. If there is any residual Rinse aid in the unit, turn the dispenser to setting 1.

Using a Rinsing Agent

You can help prevent unsightly spots on dishes and glassware, and reduce drying time by using a rinse agent. A rinse agent is specially formulated to rinse away food and detergent residues that can be left behind on your dishes. Used regularly, a rinse agent will automatically provide you with cleaner dishes every time you wash.

To fill the rinse agent dispenser, unscrew the dispenser cap located on the inner door (or on the back of the tub). Add the rinse agent slowly into the container until it just reaches the bottom of the filling cap inside the dispenser opening. Replace the cap..

Note: Clean off large particles of food sediments before placing dishes in the dishwasher.

How to use the water softener (for models with softener)

Add the salt

The hardness of the water varies from place to place. If hard water is used in the dishwasher, deposits will be formed on the dishes and utensils. This appliance is equipped with a water softener which uses a salt specifically designed to eliminate the minerals from the water.

1. Unscrew the cap from the salt container anticlockwise, which is located on the right side of the inner box.
2. Load the salt into the container. Each time you may load 250g of salt, which can be used for 15 cycles.
3. Fill the water into the salt container until a small amount of water comes out(it is very important when you use it for the first time).
4. Screw the cap back carefully.

Note:

1. Load the salt before the beginning of wash cycle so as to prevent corrosion.
2. Load the salt when the salt indicator light in the control panel.
3. Only use dishwasher salt.

Cleaning the Filters

Filter assembly

For best performance and results, the filter assembly must be cleaned.

The filter efficiently removes food particles from the wash water, allowing it to be recirculated during the cycle. For this reason, it is a good idea to remove the larger food particles trapped in the filter after each wash cycle by rinsing the semicircular filter and cup under running water. To remove the filter assembly, pull on the cup handle in the upward direction. The entire filter assembly should be cleaned once a week. To clean the coarse filter and the fine filter, use a cleaning brush. Then, reassemble the filter parts as shown in the figures below and reinsert the entire assembly in the dishwasher, positioning in its seat and pressing downward. The dishwasher must never be used without the filters. Improper replacement of the filter may reduce the performance level of the appliance and damage dishes and utensils.

Please clean the filter by blow steps when it blocked.

1. & 2. Take the filter system out from the dishwasher.

1. Disassembly the filter, then clean the coarse filter.

2. Clean the fine filter

1. Assembly the fine filter and coarse filter, then fix on the dishwasher.

Note:

Never run the dishwasher without the filters in place. When cleaning the filters, don't knock on them. Otherwise the filters could be contorted and the performance of dishwasher could be debased.

Operating Instructions

P1=Intensive Wash

P2=Normal Wash

P3=Rapid Wash

P4=3 in 1 Wash

P5=Rinse Wash

Note: The LED will default to P2"Normal Wash"each time it is switched on.

1. Press the pause/start key to start. The LED will flash the program and the washing state during operation.
2. At the end of the cycle the dishwasher will stop, the LED will stop flash, the dishwasher will beep. The LED will default to P2"Normal Wash"each time it is switched on. The power light remain illuminated, until the power (on/off) button is switched off.
3. The dishwasher is designed to stop if the door is opened accidentally during operation.
4. You can select another program during operation by pressing the pause/start key first, then pressing the program key to the desired program, and pressing the pause/start key to start.
5. After washing, dishes should be allowed to cool down for about 15 minutes so they are not too hot to handle. Dishes will cool quicker if the door is opened slightly.
6. After unloading the dishwasher, remove the filter, clean off any bits of food, and put the filter back in its position.

NOTE: At the beginning of each cycle, the dishwasher always starts in the "drain" mode. This is because the drain pump always retains a small amount of water (in the sump) from the previous cycle. This is necessary to keep the pump primed. Therefore, do not be alarmed if you see a small amount of water being pumped-out from the drain hose prior to the start of the regular wash cycle (This is normal).
