Avanti Dishwasher: Controls, Display or Error Code
A dishwasher control fault is most often the machine reporting a condition — no fill, no drain, no heat — rather than a failed board. This page takes the same fault from a different starting point: not which subsystem is likeliest on an Avanti dishwasher, but when the trouble started. This is a compact cabinet with very little air around its condenser, so clearance and ventilation outrank component failure. What ranks first here is something you can correct yourself in under an hour, which is the reason to work down the list in order rather than book a visit straight away.
What you are actually seeing
- Check your symptom against this list first.
- Settings that do not hold between cycles.
- The machine changes programme without being touched.
- The panel is lit but no programme can be selected.
- Touch buttons that respond only sometimes, or act by themselves.
- Not this fault: If the panel became unresponsive right after a hot cycle, dry it before assuming a failure.
Causes, grouped by when it started
- One entry per onset pattern first — the strongest candidate for each way this fault can begin on an Avanti dishwasher — and the remainder after them. Read the label, find the pattern that matches yours, and start there rather than at the top.
- Loose or corroded connector at the door hinge — Why: The harness crosses the hinge and flexes on every use, and a connector that has worked loose gives intermittent, changing symptoms. Compact units are put wherever they fit — alcoves, closets, garages — so installation faults are over-represented in this class. — Onset: Has been like this since the unit was installed or moved
- Steam or moisture behind the control panel — Why: The panel sits directly above a door that releases steam at the end of every cycle, and moisture behind a touch membrane produces phantom presses and dead zones. It is the classic dishwasher control fault. — Onset: Got worse gradually over weeks or months
- Control lock active — Why: It makes the panel unresponsive by design and is entered by a press-and-hold that is easy to trigger while wiping the door. — Onset: Happens on some cycles or some days and not others
- Transient lock-up after a power event — Why: A brownout or a fast interruption can leave the control in a state it will not exit, and a full power-down clears a genuine share of these. — Onset: Started suddenly, between one use and the next
What to check, and in what order
- This order follows the onset groups above, so it is deliberately different from the companion page. Neither is wrong; they are two routes through one fault.
- Pin down when it started and whether it happens every time. — Why: A fault that appeared between one use and the next has a different cause set from one that crept up over months, and this answer alone removes most of the list.
- Photograph the code before clearing it. — Why: It is the only diagnostic data the machine offers, and a reset destroys it.
- Check for control lock and clear it. — Why: Free, immediate, and it mimics every expensive fault here.
Checks you can safely do yourself
- Stop at the first step that would put a meter on live terminals.
- Photograph the display and note whether the code appeared at power-on or during a cycle. — Tools: Phone camera
About 5 min
- Look up control lock in the manual and clear it. — Tools: Owner manual
About 10 min
- Switch off at the breaker for five minutes, restore power and select the shortest cycle. — Tools: Timer
About 20 min
- Dry the panel and the top edge of the door with a cloth and leave the door ajar overnight. — Tools: Cloth — Time: 10 minutes plus overnight
Before you touch anything
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. — Id: unplug-before-service
Switch off the dishwasher at its breaker before removing the door panel or the control housing; many machines are hard-wired and a capacitor in the control can hold a charge after the power is off. Never spray cleaner onto a control panel — liquid behind the membrane is exactly the fault described here.
Where the owner checks end
Call a technician when one of these is true, and not before.
When the same code returns after a full five-minute power-down. When part of the panel is permanently unresponsive after being dried out. When the display is dark or scrambled with power proven at the machine.

What this page does not cover
Links down: - [Common Avanti Dishwasher Problems](/blog/avanti-dishwasher-problems-2)
This page is generalized: it covers the Avanti dishwasher line as a whole and does not narrow to a family, a model number or a serial range. It is also the onset-first route through this fault; a companion page works the same symptom by subsystem instead, and the two are meant to be read as alternatives rather than in sequence. The use-and-care guide covers the owner-serviceable envelope; a full service manual is not generally published for these models, so diagnosis works from the symptom rather than from a published code chart. The overview at avanti-dishwasher-problems-2 lists every problem class for this machine and routes down to the page for each; any family- or model-specific page that exists beneath this one is linked from there.
