F04 Error on Hotpoint Dishwashers

What the F04 error means on a Hotpoint dishwasher

The F04 error on Hotpoint dishwashers is usually related to a temperature sensor (NTC) fault. In practice, the appliance does not receive a reliable temperature reading and may stop the cycle or prevent it from progressing to avoid uncontrolled heating.

It commonly shows up like this:

• Programs that should heat up get “stuck” or take far too long
• The wash seems to run at a low temperature or the cycle cuts off
• The error always appears at a similar point in the program

How to clear F04 and what to check before calling service

With F04, you can rule out a temporary control glitch, but if it keeps coming back, it usually requires a technical inspection of the sensor and its circuit.

1. Complete power reset
   • Turn off the dishwasher
   • Unplug it from the power supply for 5 minutes
   • Plug it back in and test a short program
2. Avoid “brute force” testing with very hot programs
   • If the error appeared during an intensive cycle, first try a standard program
   • This helps confirm whether the fault is immediate or appears when heating is required
3. Check the basic wash conditions (so you do not confuse symptoms)
   • Clean filters and spray arms with no blockages
   • Good water inlet flow (no low pressure)
4. When it is best to call service/technician
   • F04 comes back after the full reset
   • The cycle always stops when heating or does not complete programs
   • The error appears on several programs

   In that case, the NTC sensor, connectors, and the associated heating control are checked

If F04 was caused by a temporary system glitch, it may disappear after a reset. If it keeps returning, the most efficient solution is to diagnose the temperature sensor and its circuit to restore stable wash cycles
