Overflow Malfunction Error (E12, E33)
Overflow Error (E12, E33)
Check water inlet valve
Check the wire connection to pressure switch.
Check the wires for open circuit.
Check the pressure switch
Replace the PCBs
e resistance on coil should be
between 3-5KΩ.
Replace the harness if open circuit detected.
Step 1: Check the resistance between terminal 1 and 3
with universal meter. The switch resistance will be ok if
the resistance between 20 and 40 ohm.
Step 2: Check the capacitance between terminal 1 and
2, terminal 2 and 3. Capacitance should be between 40
and 50nf
