The answer first
The first thing to rule out on a Fisher & Paykel dishwasher is the top cause below — the door or drawer latch is not proving closed — and the second is the water supply valve is closed or restricted. A dishwasher that does nothing is usually held back by a door latch, a supply or a selected state rather than by a failed control, and all three can be checked without a tool.
What you observe
- Lights come on but the cycle never begins — The latch is not proven, or the machine is in a delay or lock state.
- It hums or clicks briefly then stops — A fill or drain condition detected in the first moments of the cycle.
- 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 cycle runs but the dishes come out dirty — That is a wash-performance page, not a starting fault.
Ranked causes on this platform
- The door or drawer latch is not proving closed — Ranked first on a Fisher & Paykel dishwasher because the drawer lid seal and the door catch are the signature service items on this architecture, not an afterthought. The latch has to make a switch.
- The water supply valve is closed or restricted — Second here: the filter stack is designed to be owner-serviced and is the first mechanical thing to look at.
- A failed latch switch, interface or main board — The genuine component failures, and they sit last because everything above imitates them.
Where to start, and why there
- First: Press the door firmly closed and listen for the latch. — It sits first because the drawer lid seal and the door catch are the signature service items on this architecture, not an afterthought.
- Second: Find the valve under the sink and confirm it is fully open. — Next, and it needs no tool.
- Third: This is a meter test and is where the owner-side work ends. — Only once the checks above are clean.
What an owner can safely check
- 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
- Check the switch under the sink and the breaker — A switched outlet is the single most common cause of a dead built-in dishwasher.
Tools: torchAbout 10 min
- Confirm the water isolation valve is fully open — It is usually beside the outlet under the sink, and it is closed far more often than owners realise.
About 5 min
- STOP before removing the door panel or the kick plate to reach wiring — That is live work in a wet enclosure.
Safety first
Safety
Unplug the machine or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off, and the junction box on a built-in machine sits behind the kick plate in a wet area. Never defeat a door or drawer latch switch: it is what stops a wash cycle running with the enclosure open, and the water inside is hot.
When this becomes a service call
Call a technician when power is proven at the outlet, the valve is open, the latch engages and the machine still does nothing — the remaining candidates are the latch switch, the interface and the main board. Call an electrician instead if the outlet under the sink is dead with a healthy breaker.
