Start here
On a Fisher & Paykel dishwasher the ranking below starts where it does for a reason: the most common finding is damaged wiring in the enclosure, and the next is water reaching a connection inside the enclosure. These symptoms mean current is going where it should not, and in a built-in machine the water and the wiring are in the same enclosure — the correct response is to stop and isolate.
Symptoms, and the ones that mean something else
- The machine trips only during the heat step — A phase-specific trip, which is close to diagnostic for the element.
- The breaker or GFCI trips when the machine runs — Current leaking to earth, most often at the element or a wet connection.
- One drawer works and the other does not, or a code appears on the drawer panel — A double-drawer machine is effectively two machines, and that comparison is the best diagnostic tool on the appliance.
- NEAR MISS — the machine drains constantly but does not trip — That is a leak sensor doing its job; the controls page covers it.
The ranking that matters
- Damaged wiring in the enclosure — Ranked first on a Fisher & Paykel dishwasher because this platform reports itself — a displayed code is real information, and reading it before touching anything is the fastest route on this brand. Cabling in a kick-plate void is exposed to rodents and to careless installation of neighbouring units.
- Water reaching a connection inside the enclosure — Second here: the pump pod and the drain path sit under the drawer or basket and are reachable without a technician.
- A missing or broken earth connection — This is what turns a small fault into a shock.
The order to work in
- First: With the power off, look for damaged insulation where the cable passes into the enclosure. — It sits first because this platform reports itself — a displayed code is real information, and reading it before touching anything is the fastest route on this brand.
- Second: With the power off, remove the kick plate and look for water, staining or corrosion. — Next, and it needs no tool.
- Third: Note whether anything else in the kitchen behaves oddly, and whether the machine was recently reinstalled. — Only once the checks above are clean.
Steps you can take yourself
- Compare the two drawers, and read the code the machine is showing — On a double DishDrawer the working drawer is a control experiment: it shares the supply and the drain but not the pump pod or the lid seal, so the difference between them localises the fault immediately.
About 15 min
- Stop using the machine if anyone has felt a tingle — Switch off at the breaker and close the supply valve.
About 5 min
- Note exactly when the trip happens in the cycle — Fill, wash, heat or drain.
About 30 min
- STOP — do not open the junction box and do not keep resetting — Every reset re-energises a known fault beside standing water.
The safety boundary
Safety
If anyone has felt a shock or a tingle from the machine, the worktop or a tap, switch the circuit off at the breaker and stop using the appliance until an electrician has checked the earth. Unplug or isolate the machine before removing the kick plate — a capacitor can hold a charge after the power is off. A standard US household branch circuit is 15 A or 20 A at 120 V; never fit a larger breaker to stop a trip, and never restore power to a machine whose enclosure is wet.
When to call a technician
Call an electrician first for a shock, a tingle, or a circuit that trips with the machine isolated. Call an appliance technician for a repeatable phase-specific trip on a sound circuit, which points at the element or a pump.
