remedy
Clean the strainer.
Check the fuse/MCB in your fuse box/distribution
board.
The appliance restarts after one minute.
Check the fuse/MCB in your fuse box/distribution
board.
Remove the cause of the fault (e.g. faulty pressure
flush).
Protect the heating system against overheating by
opening a draw-off valve downstream of the appli-
ance for one minute. This depressurises and cools
down the heating system.
Activate the safety pressure limiter at flow pressure
by pressing the reset button (see chapter "Commis-
sioning").
Check the PCB and replace if required.
Check the PCB and replace if required.
Plug the flow meter plug back in.
Check the flow meter and replace if required.
Check the high limit safety cut-out and replace it if
required.
Check the heating system resistor and replace if re-
quired.
Check the PCB and replace if required.
Check the PCB and replace if required.
Reduce the cold water inlet temperature to the ap-
pliance.
