Isn't the internet a wonderful thing......
Last night
tabatha_yeddap took a look for ideas about what could be wrong with our
dishwasher and found a cure for the problem......pull it out, dip it back 45 degrees, switch it on for 30 seconds, switch it off and put it back! And what do you know - it works :)
So now the dishwasher is busy performing its role in life and washing plates and glasses......
