Ariston Aml125 - Lock Icon Flashing (And "9H", Too, If Time Set)

Hi Ed,

On these Ariston/Hotpoint washer dryers, a flashing lock light together with one of the option/delay lights often indicates a stored fault, but I wouldn’t want to guess the exact code from the lamp pattern alone. The useful thing now is to narrow down whether it’s still a door-lock circuit issue, a drainage issue, or a control board/wiring fault.

1. Isolate it from the mains first before removing any panels or inspecting internal parts.

2. Check the door and latch alignment carefully. Since the handle broke and has been replaced, make sure the door hook is entering the interlock cleanly and isn’t sitting slightly out of position. Even a small misalignment can stop the lock proving properly.

3. Inspect the new door interlock wiring. Remove the retaining band/seal front if needed and check the plug on the interlock for loose, burnt or broken wires. The fault is often in the connector or harness rather than the lock itself.

4. Check whether there is still water left in the machine. If it has failed to drain, the door can remain locked and some models will flash the lock lamp. Clean the pump filter and check the drain pump is free and not jammed.

5. Try a drain/spin or rinse cycle. If it won’t start properly, listen for whether the door locks, whether the pump runs, and whether the drum moves at all. That helps pinpoint which circuit is failing.

6. If the lock and wiring look sound, the next suspect is the main PCB/control module, especially if the lights are flashing consistently with no mechanical issue found.

If you can report exactly which lights flash and whether it drains/spins, that would help narrow it down further. For mains electrical testing or control board work, I’d recommend a qualified appliance engineer.
