Dishwasher displays H2; water does not reach target temperature, but cycle may complete.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

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

Possible Causes

Partially failing heater element, NTC sensor out of calibration, Low supply voltage, Relay contact resistance on PCB

Safety first: Disconnect power before testing electrical components.

Measure heater resistance: Compare with Fagor specifications; a significantly higher resistance than normal can reduce heating power.
Check NTC calibration: Compare NTC resistance at two temperatures (room and warm water) to ensure proper response.
Inspect PCB: Look for heat discoloration around the heater relay contacts.
Replace parts as needed: Install a new heater or NTC sensor if out of spec; replace the PCB if relay contacts are burned.
