Michael,There does not appear to be any water escaping under the machine. I ran it again. What I did notice was that when I opened the machine it was not hot! Your comments would be appreciated.
I still showed error code E09.

Hi Jan,

if the steps I sent do not help the the main board may be failing or may just have glitched temporarily.

To find out please do this:

Please turn power off to your dishwasher at the mains for 1 full hour.

That may reset the main control board if it simply just glitched electronically as they sometimes will.

Please turn the power back on at the mains after that time period and try it once again. If the problem persists you will need a new main board in the door of your dishwasher. its easy to change and no special tools are required I will help if that is the case.. hopefully this proceedure will cure the issue, but not likley.

The best place to get that new main board if needed, is Espares:

I would call to order this part because they dont list all parts they carry on site and also if you call they will ship the same day in most cases;-)

Pleas call Espares: 0844 9777 888

If you rate kindly at this time I can remain with you until we have this part replaced.

Thanks Jan.
