12-PROBLEMS AND FAULT DIAGNOSIS

Problem

Cause

Solution

The pump does not work even though 

the temperature of the collectors 

is at least 10 °K higher than the 

temperature of the tank. No sound is 

perceived from the pump.

There is no supply voltage

Check all of the line and safety cables 

(fuses)

The temperature difference for pump 

starting is set too high or the adjustment 

control unit does not show the pump 

activation signal.

•  Check the control unit

•  Check the temperature sensor

•  Reduce the temperature differential

The maximum temperature has been 

reached

Check the settings

The pump is blocked by deposits

Enable maximum pump rotation speed for 

a short period of time or unlock the rotor. 

Place a screwdriver in the gap in the pump 

unit and rotate it manually.

The pump is faulty

Replace the pump

The pump is working bit the flow 

and return sections are at the same 

temperature. The pump is very hot.

There is air in the system. The valves are 

closed

•  Check the pressure of the system

•  Bleed the system fully using the solar 

filling station

•  Open the valves

The cylinder cools down during the 

night; the flow and return sections 

are at different temperatures after 

the pump is switched off; during 

the night the temperature of the 

collectors is greater than the external 

temperature

The deadweight brakes are not fully closed 

(dirt particles)

Check the position of the red and blue 

handles. Probable presence of dirt 

particles or foreign bodies on the surfaces 

of the seal. Dismantle and clean.

The solar intake is unusually low

The pipe insulation is too thin, high heat 

loss; neither the temperature nor the 

duration of the circulation is controlled. 

The system may not have been designed 

correctly.

Check the layout of the system (dimensions 

of the collectors, shading, length of pipes, 

timer clock, hot water consumption)
