Fault Code F26: Boiling Protection

Symptom:
The program is interrupted and the drain pump is operated.
Cause:
Temperature at NTC temperature sensor has exceeded 194°F (90°C).
Remedy:
Check the heater relay and replace it, if necessary. See Section 050-4.10.
Cause:
NTC temperature sensor providing inaccurate information.
Remedy:
Replace the NTC temperature sensor. See Section 050-4.20.
Cause:
Heater relay closed.
Remedy:
Replace the heater relay. See Section 050-4.10.
Cause:
Faulty position monitoring of the automatic door lock latch.
For a switched-off appliance, the door-closing function is in operation.
Under adverse conditions, the locking system can stop in a faulty position.
The control electronic recognizes this as a "zero position" and interprets it
incorrectly. After the first (or a later) water intake, the fault loop occurs. The
machine drains for 4 minutes and, after the water intake, synchronizes the
heating relay. Spray arm heating occurs up to activation of the boiling protection.
Remedy:
1. Replace the heater relay. See Section 050-4.10.
2. Install a new electronic (SLT). See Section 100-4.5 or 100-4.6.
