Miele G1222SC F13 error code

Re: Miele G1222SC F13 error code

Heater (high presure) switch fault.
Most likely blockage of wash pump impellor. But take a look at this & do checks listed.

The program is interrupted and the drain pump operated. The display shows the message Water intake fault F13.

Cause:
On-site water supply not in order.

Remedy:
The on-site water supply should be checked by a specialist.

Cause:
Water inlet valve defective.

Remedy:
Check the water inlet valve and replace it if necessary.

Cause:
Flow meter is providing too few pulses.

Remedy:

1. Check WPS valve (filter, restrictor disc).
2. Remove the left side panel.
3. Check that the plate with the reed switch on flow meter B3/4 is seated correctly.
4. Check that the reed switch connection plug is seated correctly.
5. Replace the reed switch, if necessary.
6. Check the control lead from the electronic to flow meter.
7. Replace the water inlet mixer, if necessary.

Cause:
Water flow pressure at on-site water supply is less than 14.5 pounds per square inch (1 bar).

Remedy:

1. Check the water intake.
2. If voltage is present at the electronic for the solenoid valve, check the solenoid valve leads for continuity.
3. Check the filter at WPS valve.

Cause:
Filter in WPS clogged.

Remedy:

1. Disconnect the machine from the power supply.
2. Close the on-site water supply.
3. Unscrew the WPS from the on-site water supply.
4. Remove the washer from the threaded union.
5. Remove the filter with needlenose pliers.
6. Clean or replace the filter as necessary

I have had an intermittent F13 fault for several weeks. I checked the inlet filter and valve and eventually tried soldering a new reed switch into the inlet flow meter. This removed the F13 error but he machine started to over fill. I could see the water was lapping at the door threshold.

Running a full wash programme triggered a new F19 error which I can’t find any information on for this model. It’s either the flow sensor operating too slowly or a heater error.

The second time I tried a full programme I noticed the water was not heating. The heater element seemed fine when I tested it – about 30 ohms resistance (and not short or open circuit).

I’ve now given up and ordered a new dishwasher.
