Fisher & Paykel Dishwashers F3 Error: Element fault
Fisher & Paykel dishwasher error code F3 is a mid-severity fault meaning Heating element fault. The DishDrawer can be run on cold-water cycles (eco or rinse programs) while you arrange repair, but hot-wash programs will fault out. A power-cycle will reset the fault code.

Answer to continue safely
Is it safe to keep using?
Maybe. The DishDrawer can be run on cold-water cycles (eco or rinse programs) while you arrange repair, but hot-wash programs will fault out. Dishes will not be sanitised and heavily soiled loads will not clean properly without heat. Arrange repair within a few days.
Can I reset the code?
Yes. A power-cycle will reset the fault code. If F3 returns on the first heated cycle, the element, thermal cut-out, or heating circuit requires physical repair — the fault will not resolve itself.
When to stop immediately?
Stop if you notice: F3 returns on every heated wash cycle without exception, Any burning smell from the drawer during operation.
Symptoms You May Notice
F3 displayed during or after wash cycle
The code appears once the controller determines the water has not reached the required wash temperature within the expected time.
Dishes coming out cold and not properly cleaned
Without heat, enzymatic and heavy-duty wash programs cannot dissolve grease effectively, leaving food residue on dishes.
Cycle takes much longer than usual
The controller may extend the cycle duration attempting to compensate for the lack of heat before ultimately faulting.
Possible Causes
Failed heating element
The resistive heating element inside the wash tub has burned out, showing an open circuit on resistance measurement.
Requires ProfessionalFaulty element thermal cut-out
The thermal limiter in series with the heating element has tripped or failed permanently, breaking the heating circuit.
Requires ProfessionalWiring fault on heating circuit
A loose spade connector or damaged wire on the element supply circuit has broken the heating current path.
Requires ProfessionalControl board relay failure
The relay on the main PCB that energises the heating element has failed open, so the element never receives power.
Requires ProfessionalSafe Checks You Can Do
-
1
Power-cycle the drawer
Turn off at the wall for 60 seconds and restart. Run a short rinse-and-hold cycle and check whether F3 clears.
If the thermal cut-out tripped due to a brief overheat, a cold reset may restore normal operation temporarily.
-
2
Check for scale build-up on the element
Open the drawer and inspect the visible portion of the heating element at the base of the tub for heavy limescale deposit. A thick calcium crust can cause the element to overheat and trip the thermal cut-out.
Run a citric acid descale cycle (200 g citric acid, no dishes, 65°C program) if significant limescale is present.
-
3
Confirm water is reaching the element
Check that the spray arms are not blocked and that the water level is reaching the element. A very low water level caused by an F7 inlet fault can cause the element to dry-fire and trip.
Inspect the spray arm holes for food debris and clear any blockages with a toothpick.
When to Call a Professional
Contact a qualified technician if:
- Heating element tests open circuit on resistance measurement and requires replacement
- Thermal cut-out has failed permanently (not just tripped) and needs replacement
- Board heating relay confirmed failed after element and wiring are ruled out
