Hotpoint Ariston Programme Wheel Fail

Hi,

If the washer still runs normally on one default programme, but the programme knob no longer selects anything else, the most likely issue is either the selector knob/switch itself or the control board not seeing the selector position. It may still be repairable, but it depends which part has failed.

Before checking anything internal, isolate the washing machine from the mains.

1. Check the knob itself Remove the programme knob if it simply pulls off. Make sure it isn’t cracked or slipping on the shaft. Sometimes the plastic inside the knob splits, so the knob turns but the selector underneath does not.

2. See if the selector spindle turns properly With the knob removed, try gently turning the selector shaft/spindle underneath. If it feels loose, damaged, or does not click/index properly, the selector switch may have failed mechanically.

3. Try a reset Turn the machine off, unplug it for 10–15 minutes, then power it back up and test again. Occasionally the electronics can lock up, though this is less likely if the fault is consistent.

4. Check for signs of moisture or detergent ingress If you are confident removing the fascia/top, inspect for corrosion, damp, or residue around the programme selector and control module area. On some Hotpoint/Ariston machines, selector faults can be caused by the switch contacts or PCB connections.

5. Consider the likely repair If the knob is damaged, that’s usually cheap. If the selector switch is separate, it may be replaceable. If the selector is part of the main PCB, repair may not be economical.

So no, it’s not necessarily doomed, but the first thing to rule out is a slipping/broken knob. If the fault is on the control board, it becomes less worthwhile. For any mains-related testing or board repair, use a qualified appliance engineer.
