Control complaints on a dishwasher are usually the machine reporting a condition it cannot meet — no fill, no drain, no heat — rather than a failed board. The code names the circuit, and the circuit is usually mechanical. On a Aviva dishwasher the order below is what makes this page worth reading — the causes are ranked for this kind of machine, not listed alphabetically.
What owners actually report
- A code or a flashing light with the cycle stopped — Note the step it stopped on. That is more informative than the code on most machines.
- Buttons unresponsive or needing a firm press — Panel membrane wear, which develops gradually and is not a board fault.
- The machine beeps repeatedly with the door closed — Often a leak sensor in the base tray, which is a real finding rather than a nuisance.
- The programme restarts or jumps — A control losing its state, usually from a supply interruption.
- NEAR MISS — nothing lights at all — That is supply and door latch, which is the no-start diagnosis.
Causes in order of likelihood
- A sensed condition the machine cannot meet — First, and it covers most displayed faults: no fill because a valve or a tap is closed, no drain because the filter is blocked, no heat because the element has failed. The control is reporting accurately.
- Base-tray leak sensor triggered — Second, and it is the one owners most often try to reset away. A float in the base has detected water, and the machine has locked itself out deliberately — resetting it without finding the leak just repeats the cycle.
- Panel membrane or touch-control wear — Third. Steam from the door and years of pressing degrade the layer behind the buttons, so response becomes partial and position-dependent.
- Control board failure — Last. Genuine board faults on this appliance usually follow water ingress through the door loom, and they arrive with other symptoms rather than alone.
Where to start, and why there
- Note the step at which it halts — Fill, wash, heat or drain. Each names a subsystem and rules out the others.
- Check for water in the base tray — Tip the machine back slightly or slide paper underneath. A triggered leak sensor is a true positive far more often than not.
- Power the machine down for a minute and retry — This separates a latched state from a live fault, which changes what happens next.
The owner-side checks
- Record the code and the cycle step before resetting — Photograph the panel. Once cleared, the evidence is gone until it recurs.
About 5 min
- Switch the machine off at the spur for a full minute — The standard reset. It clears latched states and nothing else.
About 10 min
- Check the water supply and the filter — The two conditions most often reported as control faults are no fill and no drain, and both have owner-side causes.
Tools: soft brushAbout 25 min
- Look for standing water under the machine — If the base sensor has tripped, find the leak rather than resetting repeatedly.
Tools: flashlight, towelsAbout 20 min
- STOP before opening the door skin or the control housing — Both are mains-side in a wet appliance.
What has to be off before you touch it
Safety
Disconnect the power at the breaker and close the inlet tap before you open anything. Expect standing water in the sump and put towels down first; a wet floor around a powered machine is the real hazard here, not the repair itself. The door lock stays connected exactly as the factory wired it.
When to book a visit
The owner-side work is checking the supply, the filter and the base, and it resolves a good proportion of what presents as control faults. Do not buy a control board on the strength of a code. On this appliance the code usually names a fill, drain or heat circuit, and the part at the end of it costs a fraction of the board.

How specific this page is
A note on scope. This page generalizes across Aviva dishwasher families rather than naming one, so nothing on it depends on a model number and nothing on it should be read as a service-manual figure. The family- and model-specific pages beneath this one carry that level of detail; they are linked here, and if one of them names your unit it is the more specific — and more useful — answer.
