Good afternoon Patricia, my name is ***** ***** I will assist with your query today.
When the dishwasher runs do you get any error messages shown on the display, and do you hear it start filling up in the first instance?
Hi Pat, The fact your not getting an error code would suggest its not a sensor fault, as I would have expected to see E01 which would suggest a water fill error where its overfilling, this is clearly a hardware fault and not due to use error or a user setting you can change.
Based on experience I would suggest this fault is most likely due to a faulty PCB \ control module, which costs around £120 in parts (for a pre-programmed one).
If you would like me to recommend an engineer to fit this part please provide your postcode.
Further to our phone call I would suggest you use A1 Washer and Dryers on 01296 325950.
They are 9 miles from you and I have used them in the past, the charge is £25 call out and a further £25 if you wish them to do the job.
