Hotpoint wdl540p(uk)c f/l/a intermitten error code

Hello!

Was called to this machine recently which intermittenly errors mid-cycle. Customer was unable to help regards how far into the program the error was displayed. But, they did capture a video showing the error which is illustrated in the attatchment to this post.

Any ideas please?

* Everything worked perfectly when I ran the machine with quick wash upon visit. Wass element tested ok and heated, drain fuction/flow ok, spin function ok (no carbon dust around motor etc). No visible damage to module board (don’t these have a problem with module capacitor which results in flashing lights? Been a whikle sine I have worked on one of these).

Thank you.
