121 No Water Level sensor is defective or not
connected.
If the level sensor (P1) is not closed for
longer than 2 s (value between 0.2V and
4.5V), the controller terminates the
current program
with error display. The threshold values
for Input (P1) are monitored during the
program cycle.
Drain valve
Drain valve not closing. If possible, check floor drain for water flow
during wash. If drain boot suspected, do not dismantle drain valve
until replacement part available.
Replace drain boot.
Level sensor
Faulty level sensor. Check voltage at transducer. Empty level:
0.5Vdc, Working level: minimum 1.0Vdc, dynamic reading.
Replace sensor | Replace sensor board | Check wiring | Check power
supply | Check input to control board | Replace control board.
