Fault

Cause

Remedy

Flow too weak

Jet regulator furred or soiled.

Clean or if necessar y renew the fitting jet regu-
lator (see 

„2.11 Special accessories“

).

Filter soiled.

Clean the filter in the cold water inlet

after shutting off the water supply.

Heating fails to switch on / no hot water.

No electrical power.

Check the fuse (house installation).

Heating system defective.

Measure heating system resistance, if necessar y 
exchange the unit.

The pressure limiter has released

Determine and eliminate the cause for the fault. 
Disconnect from power and relieve the pressu-
re.  Reactivate pressure limiter

No electrical power.

Check the fuses in the house installation.

The turn on flow rate needed to switch on the 
heating power has not been reached. Soiling or 
furring of the jet regulator.

Clean or if necessar y renew the jet regulator
