4.11 Instantaneous
water
heater
The instantaneous water heater is installed in the water circuit for
the spray arms. When the detergent solution flows through the
instantaneous water heater, a rubber membrane attached to the
flange actuates the safety pressure switch for the heating element.
If the pressure drops, the heater switches off. The heating position is
over travelled, preventing dry heating.
Removal:
Unscrew outside door, base panel, angle strip and side panels.
Disengage the tension cords from the hinge levers. Unscrew the
screws which connect the base pan to the hinge plates. Unscrew the
rinsing tank from the rear panel of the base pan. Disconnect the door
cable harness from the plug-and-socket connection in the base pan.
Place the appliance on its back, carefully remove the base pan and
loosen the catch between the level sensor housing and the water
softening system. Disconnect the circulation pump with the rubber
support from the base pan. Open the base pan until the instantaneous
water heater can be screwed off the pump sump. Unscrew the
instantaneous water heater. Release the catch on the pump sump and
lever the instantaneous water heater off the plug-and-socket
connections of the pump sump / circulation pump.
