Hi Kevin, tried this and no luck. Model #SMS6308AU.
When I do this the Screen comes up CL and reverts to the fault h24 when I let the plus or minus button go
Tried again as you suggest but as I said before the CL comes up each time no matter how quick I do this and the h24 does not alter so may be time to call a technician to physically look at it
Left the machine unplugged overnight and tried again but the program is all locked up. Still the same response as above. h24 showing and when I press any button it comes up with the CL. Press the start key for three or four seconds and it does not clear the fault and press the plus or minus key and instead of the number decreasing it still shows the CL sign.
Have made arrangements for a local technician to look at this as it looks like the control board is frozen. Thanks.
The Technician came in today and turned the dishwasher on. He checked and got the same thing I was getting then, pressed the top left hand rectangular button which has a key symbol above it for 8-10 seconds and cleared the lock, then the delay was able to be cleared back to h00 and it reset the machine. He said pushing the start button for 3-4 seconds will reset the machine but not clear the Child lock.
