e. If however the heater pressure switch B1/13 switches, the wash program is
interrupted immediately, the drain pump runs, and Fault F19 is registered.
6.8.15 Wash Program Is Interrupted And Drain Pump Is Operated
If an F18 fault is displayed
The water inlet valve is open when it should not be (signal to open it has not been
given by the electronic module). Water then flows into the appliance and unexpected
pulses from the flow meter B3/4 are detected.
1. Check the Water Inlet Valve for proper operation (may be stuck in open position).
a. Gain access to the water inlet valve.
b. Start a wash program
c. Place your hand around the inlet valve during the water inlet step.
You should feel a vibration indicating that the valve is energized.
d. At the end of the water inlet step the valve should be de-
energized. If water is still entering the machine, replace the water
inlet valve.
e. Check for interference pulses. Electrical components within the
water diverter could be interfering with the pulses produced by the
flow meter. Troubleshoot accordingly and replace the water
diverter if necessary.
If an F14 fault is displayed
With the circulation pump operating after a water intake step, the heater pressure
switch is checked to ensure that sufficient water pressure exists in the wash water
circuit. For this the heating relay must have been activated.
1. During a heating step the heater pressure switch may have registered no or
insufficient water pressure at the circulation pump.
a. Check the dispensing of detergent and rinse aid. Excessive foam
development means that the pressure at the heater pressure
switch will be less.
b. Check for correct water level within the machine (water level
should be just under the filter arm).
• If incorrect water quantity is registered, see “Inlet/Drain LED flashes during
water intake” for troubleshooting steps.
c. Check the filters for blockage.
