1. Check the power plug and outlet as often as possible. Secure electrical 
contact and also proper grounding must be provided. The plug and outlet 
must not heat excessively.

2. If the water heater is not used for a long time, especially in regions with 
low air temperature (below 0°C), it is necessary to drain water from the 
heater .

3. To ensure long reliable water heater operation, it is recommended to 
regularly clean the internal tank and remove deposits on the electric heating 
element of the water heater, as well as check condition of the magnesium 
anode and, if necessary, replace it with a new one.

4. Preventive operations must be performed upon strict observance of the 
operation manual and safety precautions.

5. The water heater is equipped with a thermal switch, which cuts off power 
supply of the heating element upon water overheating or its absence in the 
water heater. If the water heater is connected to the mains, but water is 
not heated and the indicator doesn’t light up, then the thermal switch was 
switched off or not switched on. To reset the water heater to the operating 
condition, it is necessary to:

- de-energize the water heater, remove the plate of the side / lower cover 
for horizontal-type/vertical-type water heater respectively. 

- for FSL2/FSP2 series horizontal-type water heaters: press the button, 
located in the center of the thermal switch, placed near the heating element 
(with a round shape), until it clicks, Fig.12;

- for FSL1/FSP1 series vertical-type water heaters: unscrew retaining nut of 
the thermal switch, fastened on the flange of the heating element, turn the 
thermal switch and press the button, located in the center of the thermal 
switch, until it clicks; Fig. 13;

- if the button is not pressed and there is no clicking, then you should wait 
until the thermal switch cools down to the initial temperature.

6. To drain water from the internal tank properly, you need to use the drain 
hole (only for FSL2/FSP2 line) (it is necessary to unscrew a plug, covering 
the drain hole), water can also be drained through a composite relief valve 
(Fig. 11) (unscrew the composite relief valve drain knob screw and set the 
drain knob to the upper position, at that hot water tap must be open, and 
cold water supply valve must be closed).

7. Bear in mind to check serviceability of the relief valve every 14 days – 
inspection method:

- turn the discharge lever to the left up until you feel the change of thread, 
then water must start flowing from the valve’s hole. After checking the 
water flow, return the lever to its initial position.

8. If necessary, wipe external surfaces of the heater by a damp cloth with 
soap.

IMPORTANT! 

The manufacturer provides an extended guarantee 

for particular water heater components provided that 

timely and proper routine maintenance is performed 

by specialists of an authorized service center (see the 

guarantee card).

IMPORTANT! 

If these actions had no positive result or the thermal 

switch turns off repeatedly during a short period of 

time, then you should de-energize the water heater, 

cut off water supply and contact your local Timberk 

Authorized Service Center for a consult or repair of the 

appliance.

Failure

Possible causes

Troubleshooting method

Heating indicator light doesn’t light up, 
water is not heated

1. Temperature adjustment device 
is broken.

Contact a repairer, TIMBERK service 
center.

2. Temperature limiter was actuated or 
was not switched on.

Switch on the temperature switch 
following instructions on its activation. 
(page 12)

3. Temperature limiter is broken.

Contact a repairer, TIMBERK service 
center.

Water doesn’t flow from the hot water 
discharge cock

1. Water feed is cut off.

1. Wait until water supply is restored.

2. Water pressure is too low.

2. Switch on the water heater again, 
when normal water pressure restores.

3. Water supply exhaust valve is 
closed.

Water temperature is too high

Water temperature control system 
is damaged.

Contact a repairer, TIMBERK service 
center.

Water leakage

Seal at the point of pipe connection 
is broken.

Replace the joint seal.

Water flows from the appliance’s case

Breaking of the internal tank 
(corrosion)Seal at the point of the 
heating element connection is broken.

Transportation and 
storage

From -30° to +50°

From 15% to 85% 

(without a condensate)

We are exploring new technologies and we constantly improving the quality 
of our products. That’s why specifications, design and accessories are 
subject to change without any specific notice.

3. Temperature display (only for FSP series)

All FSP series models are equipped with temperature display shows 
current water temperature in whater haeter tants. 

IMPORTANT! 

Water may start dripping from the relief valve hole 

during heating. It is impossible to avoid water leakage 

and you must not prevent it since valve blocking 

may cause rupture of the internal tank (in case of 

equipment failure).
