Thanks! It defies my imagination that this could be related to the frequency of our dishwashing. Every other night isn't exactly infrequent; I probably used our 25yo Whirlpool that this replaced more sporadically and we never had a problem.

I don't know if there was a high loop preinstalled; I looked up the installation manual for my model and it doesn't mention one. It does say the hose should be looped or connected to an air gap. The minimum height required is 20", which is just about the height where the hose enters my sink cabinet, but it then dips to the floor instead of being elevated as in the snippet below from the Bosch manual.

My filter is always clean, there has never been much water in the dishwasher sump, and the fact that this problem revived while I was using the GD makes me suspicious that it's not really a dishwasher problem, but a problem of water or food running thru the GD into the dishwasher due to bad installation. But that's the equivalent of practicing medicine via Google.

I could elevate the hose myself, but I can't figure out how to get to any blockage in the dishwasher drain, so I'm going to have to call a professional either way. But if I'd figured this out the last time, I would have at least avoided a repeat visit.

I have never "high-looped" any of the drain hoses on my dishwashers - that's what the non-return valve in Bosch, Miele and other Euro dishwashers is for. Anyway... E:15 relates to the dishwasher having detected an internal leak (google Bosch dishwasher e 15) and is not related to drain blockages, which would trigger another error code.

When I wanted to install an air-gap, I just got a hole saw and cut a hole in the counter where it could go and installed it myself. If you have tile or granite you will need a pro to do the job, but it is a one time fix. I could choose between many brands and I got one that matched the finish on my faucet. soap dispenser, and instant hot water tap (brushed stainless steel). Now we have a new counter and my wife wanted dual stainless steel sinks so I ordered one with enough mounting holes for everything.

Thanks @whirlpooltrainee & @nerdyshopper. I made an appointment with a tech from a Bosch-affiliated shop coming by at the end of this week.

In the meantime, I had my regular repair guy (who'd cleared the problem last time) and he said it should have been high-looped (which is what the installation manual says as well).

So he made that fix and reset the machine so that it works. But he also indicated that there was water collecting at the bottom of the tub and that he thought the control panel was wonky. I'm keeping the Bosch warranty appointment for this week to make sure that I get it fully checked by an expert.

The E-15 error message indicates the dishwasher is detecting extra moisture and a possible leak. This can also happen if the air around the dishwasher is humid, which was the case for me. I waited a couple days for the moisture around the machine to evaporate and it started to work again.

I am debating between a Bosch 500 or 800 dishwasher? After rebate, it is only $50 difference. The 800 series have more electronics, which have better chance to break.

Is it better to get the 800 series over the 500 series?

Which models?

Get the one you like better. The main electronic module is the same between these two - and most Bosch dishwashers anyway. It's just a matter of which cycles are stored on it. The 800 control panel seems touch control, in which case you *could* even argue that it's better sealed against moisture than buttons. Other expensive parts like the wash pump are also identical between these two and, again, most Bosch dishwashers.

Thank you.

another question. :) why does the Bosch dishwasher come with junction box instead of power cord? Is there a reason for that? It is pain to install with a junction box.

I've been getting the water tap error and cannot fix it. I've emptied the bottom and cleared the hose of any water and still get the error. My skills stop there. Help.

I thought the junction box thing was a bit odd also, but you can get a regular power cord for about $20. I just cut the cord off the dishwasher I was replacing and stripped the wires back and used the junction box. Took all of five minutes, if you have a cord you can use.
