I have an Aquarius WT 540 washing machine. There is flashing lights on the machine. The power on/off light flashes quite rapid and all lights flash steadly.

We stock the modules for these at £53.88 + £6 postage (exchange). This is ready programmed for your model number (that's important otherwise it will not work). To order, go to our website at www.emwelec.co.uk and put WT540 in the search box or call us on 01159652118. You will still have the option of returning the module within 14 days for a refund (less our handling of £12) if it does not sort out the problem. Tony EMW Electronics

It took all of 2 minutes to find those resources. All I did was a Google search for "Hotpoint Aquarius WT540 flashing"

WHy couldn't you have done that?
