Malfunctions and troubleshooting
Remedy
Connect measuring cell
Temperature must be > 0°C
Check measuring cell, change if necessary
Check wiring, change if necessary
Check measuring cell, change if necessary
Temperature must be < 100°C
Check wiring, change if necessary
Check measuring cell, change if necessary
Check wiring, change if necessary
Install the measuring cell and its cable away from
possible sources of electromagnetic interference:
n Lay the measuring cell cable as far away from
the dishwasher pump motor as possible.
n Do not lay measuring cell cables together with
high-voltage cables in a cable duct.
n Do not install the measuring cell and its cable
near frequency-controlled motors, mobile phone
antennas or WLAN antennas.
Remedy
Where applicable, pump back-pressure too high: Check hydraulic
lines, where applicable rinse.
Check connecting cable.
Motor defective, change
Where applicable, pump back-pressure too high: Check hydraulic
lines, where applicable, rinse.
Check connecting cable.
Motor defective, change.
