Electrical instant water heater

EN

Upon energization, the power 
indicator does not light up.

The power indicator lights up, 
but water is not heated.

Water does not flow from the 
hot water outlet.

Water leakage.

Water at the outlet from the 
water heater is sometimes 
hot, sometimes cold.

There is no power supply.

1. Water flow rate is less 
than necessary.

2. The power mode switch 
is off.

3. The temperature limiter 
set at 85°C is tripped due to 
overheating.

4. Too low water pressure in 
the water supply network.

5. Low voltage of electrical 
network.

1. Water feeding is shut off.

2. The cold water inlet valve 
is not opened.

Problem with tightness of 
connections.

1. Unstable water pressure.

2. Water temperature at 
the outlet from the water 
heater is too high causing 
repeated tripping of the 
overheating protection 
device.

Make sure that power supply is 
switched on.

1. Increase water flow rate.

2. Place the On/Off/power 
control knob to the ON position 
(      ).

3. Wait until the temperature 
limiter set at 85°C cools down 
and reactivates.

4. Wait until normal water pres-
sure is restored in the network.

5. You need to wait until the 
voltage will be stable.

1. Wait until water feeding is 
restored in the water supply 
network.

2. Open the cold water inlet 
valve.

Restore tightness of connec-
tions.

1. Use the water heater only 
after stabilization of water 
pressure.

2. Decrease heating power, 
increase water flow rate.
