Quick answer
Fisher & Paykel links F4 on a DishDrawer to a failure of the element that heats the water. There is no home fix: switch the drawer off at the wall, note the code and model, and book a service.

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Element measurement
What they doWith the drawer unpowered, the technician measures the element and its insulation against Fisher & Paykel specification and checks its connections.
They must show youthe measured value against the specification.
In writingwhat was measured, the result and the reference of any replaced part.
Heating test
What they doAfter the repair, the technician runs a heated programme and checks it finishes without F4.
They must show youthe finished programme with no code.
In writingthe test and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

Code and model for the service
No special tools
Procedure
- Who:
- you.
- How:
- take a photo of the code on the drawer and have the model details ready, as Fisher & Paykel asks to speed up the service.
- Result that matters:
- knowing which drawer shows the code and the model.
- If there are two drawers and only one shows the code:
- note it; it helps the technician.
- If several codes appear:
- photograph them all.
- Evidence to keep:
- the photo and the model with the date.

No special tools
Procedure
- Who:
- you.
- How:
- switch the dishwasher off at the wall before opening or looking into the drawer, as Fisher & Paykel says.
- Result that matters:
- no power to the drawer while you look at it.
- If you see water outside the drawer:
- also turn off the water and say so when you book.
- If there is no water outside:
- leave the drawer off until the visit.

Result of the last wash
No special tools
Procedure
- Who:
- you.
- How:
- without opening anything, recall or check whether the dishes from the last programme came out cold or poorly dried.
- Result that matters:
- giving the technician the symptom along with the code.
- If they came out cold:
- that fits a heating problem; say so when booking.
- If they came out warm:
- say so anyway; the fault may be intermittent.
- Evidence to keep:
- a note of the programme used and the result.

What it means
In the Fisher & Paykel list, F4 is a heating element failure on the DishDrawer. For F4 the manufacturer gives no home checks: it says a service technician is required and to book a service. The element runs on mains power next to water. The code points to the heating circuit, but on its own it does not prove the element is broken: its connection or the control that powers it can also fail.

Symptoms and causes
Probable causes · in order
- Failed heating elementCommon
This is what Fisher & Paykel names for F4. Only a technician measurement with the drawer unpowered confirms whether the element is open or leaking to earth.
Evidence: F-code displaying on DishDrawer Dishwasher
- Heating connection or controlPossible
With a sound element, the fault may be in its wiring or in the electronics that power it. The code does not separate them; the measurement does.
