If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Wrong type of NTC installed, NTC sensor aged or drifted, Poor contact between NTC and tub, Wiring resistance affecting reading

Safety first: Disconnect power.

Verify correct part: Ensure the replacement NTC (if previously changed) matches the original Hansa specification.
Check mounting: Make sure the NTC is fully seated and in good thermal contact with the tub or heater pocket.
Measure resistance curve: Compare NTC resistance at two temperatures (room and warm water) with manufacturer data. Replace if significantly off.
Inspect wiring: Repair any corroded or extended wiring that could add resistance.
