Frequently Asked Questions - BWI45S1D-242 BEKO

How do I install the Beko BWI45S1D-242 water heater?

Installation must be carried out by a qualified professional. The water heater should be mounted vertically on a wall with sufficient strength. Ensure the electrical and water connections comply with local regulations. Always use the included safety valve.

How do I set the temperature on my Beko water heater?

Turn the thermostat knob located on the front panel. The temperature range is 30°C to 75°C. A medium setting of around 60°C is recommended for optimal efficiency and to prevent bacteria growth.

What should I do if there is no hot water coming out?

First, check that the power supply is on and the circuit breaker hasn't tripped. Verify that the thermostat is set correctly. If the problem persists, the heating element may be faulty and require replacement.

How often should I descale the water heater?

Descaling is recommended every 6 months in areas with hard water. Use a suitable descaling solution and follow the instructions in the manual to avoid damage to the tank.

What safety features does this water heater have?

The Beko BWI45S1D-242 includes overheat protection, a pressure relief valve, and a thermal cut-out to prevent dangerous conditions.

Can I use an extension cord with this water heater?

No, it is not recommended to use an extension cord. The water heater must be connected directly to a dedicated electrical outlet with the correct rating (220-240 V, 2000 W).

What is the energy efficiency class of this model?

The energy efficiency class is C. While not the highest rating, it provides adequate performance for standard use.

How do I clean the exterior of the water heater?

Wipe the exterior with a damp cloth and mild detergent. Do not use abrasive cleaners or solvents. Ensure power is turned off before cleaning.

What should I do if the water heater is leaking?

Turn off the power and water supply immediately. Check if the leak comes from a connection or the tank itself. If from a connection, tighten it. If from the tank, the unit may need replacement. Contact a professional.

Are spare parts available for this model?

6 Plumbing Procedure

CAUTION!

This Instant Hot Shower is a single point system and the 'Water Outlet' can only be fitted to the PVC Hose and Handshower set provided. NO CONTROL VALVE OR FITTING CAN BE FITTED TO THE WATER OUTLET.

6.1 Connect the Stop Valve to the Water Inlet with rubber water. use proper tools to tighten the connection and be careful not to break the plastic nut.
6.2 Connect the incoming water piping to the Stop Valve (1/2" BSP). Make sure to put the Mesh Filter between Stop Valve and incoming water piping.
6.3 If in any case, the Stop Valve is not use or omitted, make sure to put the Mesh Filter between the heater unit inlet pipe and incoming water pipe.
6.4 Turn on the water main to drain out all the plumbing dirt, at the same time fill up the heater tank.

IMPORTANT

For Pump Model, it is highly recommended to connect Water Inlet Connection to tank storage supply, otherwise it may cause damage to the Pump Motor.

6.5 Turn on the water main to drain out all the plumbing dirt, at the same time fill up the heater tank.

THE HEATER TANK MUST BE FILLED UP WITH WATER BEFORE TURNING ON THE ELECTRICITY SUPPLT TO PREVENT ANY DRY BURNT DAMAGE TO THE HEATING ELEMENT.

6.6 Connect the PVC Hose and Handshower tot he outlet of heater, be sure to put in the Ruber Washer.
6.7 Hook the Handshower to the Slider Rail Shower Holder and adjust to your ideal position.
6.8 Check if any water leakage.
6.9 Do not use white tape during installation.

WARNING!

6.10 THE WATER INLET AND OUTLET MUST BE INSTALLED CORRECTLY, OTHERWISE HEATER UNIT WILL NOT FUNCTION.

6.11 DO NOT APPLY PLUMBING CEMENT ON CONNECTION. WHENEVER NECESSARY, USE ONLY THREAD OD SEALING TAPE.

7 Electrical Installation

WARNING!

7.1 This appliance must be earthed. Improper grounding could cause electrical shock.
7.2 Remember to SWITCH OFF the mains before carrying out any electrical work.
7.3 Refer to TABLE 1 for the correct cable size.
7.4 Use double insulated cable of over 2.5mm ^4 .
7.5 Lead the power cable from MCB to a "ON/OFF" double pole Linked Switch having a contact separation of at least 3mm in all poles outside the bathroom, then lead a cable to the terminal block inside the Heater Unit. (Fig. 4)

PROCEDURE :

7.6 Insert the wall embedded cable through Side Entry 'A' by cutting a hole at the source cord rubber holder and lead the cable to Cable Bracket 'B'. (Fig. 6)

METHOD OF ALIGNMENT WHEN REPLACING FRONT COVER

8 Test Run

8.1 Turn on the water supply and Stop Valve, the water will flow through the Handshower.
8.2 Switch on the electrical supply. The 3 LED Indicator lights shall run ON/OFF 3 times in sequence to indicate the set are self checking.
8.3 Turn the Temperature Control Knob to 'ON', the Red Indicator light (HEATER) will turn on, hot water will flow out within a few seconds. The More Temperature Control Knob being turned in clockwise direction, the hotter is the shower.
8.4 The shower might not be hot enough even at 'MAX' position if incoming water supply from the mains is too cold or the pressure of the water is too high. In this case, you may adjust the Stop Valve to reduce the water inflow in order to get the desired showering temperature.
8.5 Check the Built-in-ELCB as following :
- Press the "TEST" Button, the Built-in-ELCB should trip and cut off the power supply, all LED Indicators should light off.
- Press the "RESET" Button, the 3 LED Indicator lights shall run ON/OFF 3 times in sequences to indicate self check as in 8.2 above and the Heater unit should resume normal function, the Green LED indicator should light on.
If procedures stated above prevailed, the ELCB is functioning in normal condition.
8.6 The height and direction of Shower Holder are adjustable by realeasing the shower holder knob clockwise and anticlockwise.
8.7 It is unnecessary to turn the Temperature Control Knob to "OFF" position when the Heater is not in use.
8.8 Switch OFF the electricity supply after shower.
8.9 For Pump Models:
Turn on the Pump Control Knob to test on Pump's functionality. If the shower is not hot enough, you may adjust
the pump speed until the desired shower temperature is obtained.

9 Handshower Spray

This innovative adjustable Handshower has 3 different spray patterns (STANDARD, SOOTHE and JUMBO). The patterns are described as following:

Clean the Handshower Head holes by using the soft brush from time to time.

(Recommended once a week)

Note: Take care not to damage the holes of the Handshower Head during cleaning.

10 Maintenance

Read the section'SAFETY INFORMATION' first.

10.1 TEST THE 'ELCB' REGULARLY (This procedure is highly recommended test at least once a month)

Turn on the electricity and water supply, both RED (HEATER) and Green (ELCB) Indicators will light up if the Temperature Control Knob is in 'ON' position. Press the ELCB Test Button, both HEATER and ELCB Indicators should go off. Press the Rest Button to resume the electricity supply.

10.2 CLEAN THE FILTER REGULARLY

Clean the Mesh Filter regularly to prevent blockage. (Fig. 10) Remove the Built-in-Filter by turning its cap anticlockwise. Whenever need to flush the internal stainer with water to remove any trapped sediments. Whenever fixing back the Buily-in Filter, beware of the alignment of Internal Strainer. Use the protruded guideline within Stop Valve to position the Internal Strainer.

WARNING!

10.3 If the HEATER Indicator does not go off when you press the ELCB Test Button, switch OFF the mains supply and contact Beko Call Centre for repair service. NEVER try to repair the unit by yourself.

10.4 CLEANING PRECAUTION!

Do not use thinner, alcohol, petrol or any other organic solutions to clean the set. Use only damped cloth with mild detergent.
