Frequently Asked Questions - KT3655 Malmbergs

How do I adjust the temperature on my KT3655 boiler?

Use the thermostat dial on the front panel. Turn it clockwise to increase temperature (max 75 °C) and counterclockwise to decrease. Wait a few minutes for the water to heat.

What should I do if the boiler trips the circuit breaker?

First, reset the breaker. If it trips again, unplug the boiler and check for a short circuit or water leakage. Contact a qualified electrician if the problem persists.

How often should I descale the boiler?

Descaling is recommended once a year, especially in hard water areas. Use a descaling solution suitable for electric water heaters and follow the manufacturer's instructions.

Can I install the boiler myself?

Installation must be performed by a licensed professional plumber or electrician to ensure compliance with local regulations and safety standards.

Why is my water not getting hot?

Check the power supply, thermostat setting, and if the circuit breaker is on. If these are fine, the heating element or thermostat may be faulty and require replacement.

What is the purpose of the pressure relief valve?

The pressure relief valve automatically releases excess pressure from the tank to prevent explosion. If it leaks frequently, it may indicate a problem with the pressure or the valve itself.

How do I replace the magnesium anode?

Turn off power and water supply, drain the tank, unscrew the old anode from its mounting, and install a new one. Check the anode annually; replace if more than 60% corroded.

Is the boiler suitable for outdoor installation?

No, the KT3655 is designed for indoor use only. It has an IP24 rating, meaning it is splash-proof but not weatherproof.

Why does my boiler make a knocking noise?

Knocking is often caused by sediment buildup in the tank. Descale the boiler to remove limescale deposits. If noise persists, the heating element may need replacement.

What spare parts are available for the KT3655?

Common spare parts include the heating element, thermostat, magnesium anode, and pressure relief valve. Use only Malmbergs-approved parts to maintain safety and warranty.

BEFORE THE FIRST OPERATION

Please read the operating instruction carefully.

Before using for the first time, boil fresh water at least twice in the appliance in order to clean any residue left from the manufacturing process.

OPERATION

Always remove the jug from its base before filling it.

Open the lid by pushing at the locking button and fill the tank with fresh • water, paying attention not to fill under the minimum mark and above the maximum mark in the water gauge. (You can see the level by the transparent water gauge on the body.)

Close the lid by pressing it down until it you hear a click. Make sure it • closes correctly.

Put the kettle onto the base, plug into the wall socket and switch on, then • the indicator lamp lights up.

The jug kettle will switch off automatically when the water has boiled.

Disconnect the kettle from the base, pour out the hot water with the lid • closed.

CLEANING AND MAINTENANCE

Make sure the appliance is unplugged from the supply socket and fully • cooled down before cleaning.

To clean the exterior surfaces, slightly wipe over with a soft damp cloth • and dry thoroughly.

To clean the inner walls of the kettle, use a soft damp cloth or a soft brush • to remove the dirt.

Note: Never use abrasive products.

To clean the filter, open the lid and pull the filter out from the interior •

body, then rinse with running water and dry it thoroughly before reassembling.

Never immerse the jug kettle or its base in water.

DESCALING

The appliance has to be descaled regularly to ensure optimum performance. The frequency depends on the water hardness and the boiling frequency.

1. If you begin to notice the increase of the noise during boiling, or the kettle switches off before boiled, this indicates that descaling is necessary.

Generally, the descaling should be done in the following periodicity:

With soft water, at least once every 6 months.

With hard water, at least once every 3 months.

1. It is highly recommended to use only descaling agent suitable for plastic kettles.

2. Read carefully the instructions of descaling agent then operate the descaling process step by step.

3. After the descaling, rinse the inner of the kettle thoroughly with clean water.

Note:

1. Never use vinegar as descaling agent.

2. In case of doubt concerning the water hardness, ask your local tap water company.
