[QUOTE 4036435, member: 76"]I have a Bosch dishwasher, this afternoon the display showed E15, which didn't seem good, the pump was running but water was being fed. I tried a reset, unplugging all sorts, no joy. The call-out fee for a local engineer is £'s and I can't afford that this month. So, I Googled the error message and read the first response. "Pull the dishwasher away from the wall, with it switched on, tilt it backwards a good way, put it down and it should be fixed."
Oh yeah right mate, like that's going to bloody work, you muppet. Sooooo I pulled it away from the wall, switched it on, tilted it back and 'whirrr, clunk, whoosh, whirrr' error message gone, unit working perfectly
That must have saved me dozens of £s, thank-you anonymous engineer man

E15 - had a huge saga with that error message last year, so I can share the following:
First of all - if you are out of manfacturer's warranty DO NOT, UNDER ANY CIRCUMSTANCES, use KNOW HOW (Curry's Dixons's fix people). Long long story - over 6 months - featuring dozens of calls, emails and Tweets (name and shame on Twitter and you get quick responses) 8 visits, 6 different call centres, 5 different customer service cases, 2 floods, 1 torn kitchen floor and still no working dishwasher. However, they eventually did replace my machine after I threatened them with BBC consumer department intervention.
Second - the issue could be that your dishwasher's tank (which recycles the water during running) that may need replacing due to limescale and/or salt deposits building up over time, and the water not being able to drain quickly enough, giving you the alarm and the breakdown. The SEVENTH engineer who came to look at mine - a local one, not one of the KnowHow muppets - discovered as much.
So, if it goes again, and you bring in a local engineer, rather than one from a big company, get him to check the tank. I don't know what the replacement cost might be, but it could be cheaper than replacing the entire machine.
Or it might be worthwhile getting Bosch itself out for their fixed price service. May be a bit more expensive, but at least they know at what they're looking.
