Problems and trouble-shooting
problem
cause
solution
Pump is not working although
the collector temperature is at
least 10K warmer than that of
the tank. No sounds from the
pump can be heard
No power
Check all pipelines and fuses
Either temperature difference is
adjusted too big or the control-
ler does not switch
- check controller
- check temperature sensor
- diminish temperature difference
Maximum temperature is achie-
ved
Check settings
Pump shaft is blocked by depo-
sits in the bearings
Either switch to maximum rota-
tion speed for a short time or
unblock rotor. Put screwdriver
into slot and turn manually
Pump is broken
Exchange pump
Pump is operating, but flow and
return have the same tempera-
ture. Pump is very hot
There is air in the system.
Valves are closed
- check system’s pressure
- flush complete solar system
with Solarbayer filling station
- open valves
The tank cools down during the
night; flow and return have dif-
ferent temperatures after the
pump has been turned off; du-
ring the night collector tempera-
ture is higher than outside
temperature
gravity brakes do not close
100%
Check the position of the red
and blue handle.
Probably jammed cuttings or
particles of dirt on the sealing
surface
The solar gain is unusual low
The pipe insulation is too thin,
high heat loss; circulation is
neither temperature nor time
controlled.
the system may have be
designed incorrectly
Check the layout of the system
(collector size, shading, pipe
length, clock timer hot water
consumption)
