Dishwasher displays E3; cycle ends quickly with dishes still dirty and cold.

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

Failed heater element, Faulty NTC sensor, Heater relay failure on PCB, Loose heater wiring

Safety first: Disconnect mains power and allow the unit to cool before accessing the heater.

Visual inspection: Remove the lower panel and inspect heater wiring and connectors for burning or looseness.
Continuity test: With a multimeter, check resistance across the heater terminals. An open circuit indicates a failed heater.
NTC check: Measure NTC resistance at room temperature and compare with Fagor specifications.
Board diagnosis: If heater and NTC are good, the control board heater relay may be defective and the PCB should be replaced.
