Cause
The strainer in the appliance is dirty.
One phase down.
cuts out temporarily.
The safety pressure limiter has tripped.
The PCB is faulty.
The PCB is faulty.
The flow meter (DFE) is not plugged in.
The flow meter plug is faulty.
The high limit safety cut-out has responded or suf-
fered a lead break.
The heating system is faulty.
The PCB is faulty.
The outlet sensor has been pulled off. A lead is
broken.
The cold water sensor is faulty.
The cold water inlet temperature exceeds 45 °C.
The outlet sensor is faulty (short circuit).
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 "Installa-
tion / Commissioning / Initial start-up").
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 if
required.
Check the heating system resistor and replace if
required.
Check the PCB and replace if required.
Plug in the outlet sensor or replace if required.
Check the PCB and replace if required.
Reduce the cold water inlet temperature to the ap-
pliance.
Check the outlet sensor and replace if required.
