Or something like that ? Have you tried a DW cleaner see if that helps?

I have noticed it varies a lot on my DW depending on what's in it and there seems to be no sense or reason to it

If you do find anything please let us know.

Rinse aid?

A Bosch dishwasher will automatically increase dry time and final rinse temperature to compensate for lack of rinse aid. However, if there is rinse aid and it isnít throwing a code I have no clue other than very cold intake water temp.

Heater that boost inlet water temp???

DW don't get hot on the front panel while washing like it used to. Even the counter top got a little warm. I think it's something to do with the heater that boost inlet water temp. up etc.

I found on internet some have found the control board with burnt solder joint going to water boost heater (all solder burnt off/ no connection). They clean and re-soldered the spot on control board and the heater went back to working. If not that then most likely the heater bad.

I going to take a look at the control board......

Yes, if it can't get up to temp (either an issue with the heater or too low a water level, thus the heater safety switch is triggered) the run time will increase. Frequently, the display will also stall at 0:01 minutes.

Possibly the 'water matrix to sump transfer corrugated hose' is crudded up with grease. This causes the water measuring/high water level detectors to be confused.

Item '0424', is the corrugated hose. It connects between the fill assembly (0426), and the sump unit. You can see the exit point of the hose with the filters removed, at the 6 o'clock position

You can carefully and - GENTLY - rod it out with a long, narrow bottle brush.

Bear in mind that it curves off left and upwards at the same time. And it is quite a delicate hose, and can be dislodged. You'll probably discover grey, greasy gunge.

FYI, that sounds like the issue that caused the big recall a few years ago. Dishwashers were catching on fire, and in some cases, causing house fires as a result. If yours has failed this way, or is from that era, you might want to contact Bosch instead of having it repaired.

www.cpsc.gov/Recalls/2018...

When we moved into our house a few years back, it had a Bosch dishwasher that was part of the recall. We were offered either a free replacement of the control panel with redesigned parts, or a significant discount on a new machine. We took the opportunity to upgrade, and went with the second option.

I bought my Bosch SHU43C about 15 years ago. It was discounted at Sears, apparently either a discontinued model or a return. In any case, it's been great. However a few years after purchase - and it was running just fine - I got a letter from Sears saying there had been a safety recall. They sent out a tech who replaced the control board (or some part of it). As I recall, it was for a problem similar to what's been described here: potential for fire. One thing changed - the quick wash time changed somewhat. Not a problem for me, since I rarely use that option.

A year or two ago it started not draining completely. Not a clogged screen or drain pipe. I wound up having to replace the drain pump. Wasn't too expensive for the replacement, as I recall, maybe about $25. The worst part was getting the DW out from under the counter. The kitchen counters here had been installed onto the original flooring. Then, later, the previous owner had new linoleum installed, over 1/2" particle board underlayment. That raised the floor enough to make the DW a tight fit vertically. It actually sits in a 1/2" deep recess under the cabinetry.

Eventually I'm going to redo the flooring - with some sort of tile. Hopefully it will drop the floor height to where it should be. Although I'm not counting on it! I certainly don't want to have to replace the countertops/cabinets.

15 years and one inexpensive DIY repair...that's pretty good.

 

How often do you run it?

I run the Bosch about 2-3 times a week. I usually wait till it gets a full load. I consider it a superior design, with the heating element hidden in the water supply so it can't melt most plastic items. If this one finally dies and it too expensive to fix vs. a new one, the next new one will be a Bosch, Miele, or LG with similar hidden heating elements.

OTOH, I have a nice KA Superba vintage machine in storage, and it would be all sorts of fun to stick that in the kitchen under the counter for a while.

Additionally, I have two vintage working KA/Hobart free-standing DW's, which live in the patio kitchen. I rarely run them, but they are there if I need them, just in case.

Life is good with plenty of extras ;-).
