I have an integrated Diplomat dishwasher which has been acting peculiarly for some time now, it didn't seem to know when to switch off and kept washing.

Someone suggested using Finish dishwasher cleaner in case there was a blockage, which we've done.

Now the dishwasher is blowing a fuse when we try to use it.

Any suggestions before I have to call out a repairman.

The dishwasher is approximately 9 years old.
