Bosch dishwasher

The conclusion is specious; there's no "float" in most washing machines yet they manage to have repeatable fill levels (regardless of whether they have clothes in them at the time, or not!). I.e., the float is not sitting out there for all to see! :>

Pull the dishwasher out so you can access the back/sides. You'll see a bit of plumbing and an odd-shaped plastic "container" (sorry, I don't know how else to describe it). Check it for crud, etc.

There is a Youtube demo at

There is no float chamber, no float switch and no back cover.

Please indicate by giving me the part number:

A quick glance at the drawings doesn't show the "container" I've seen. On the models I've examined, there's an odd-shaped "reservoir" of sorts with the float switch inside (i.e., wires and hoses going to it -- I don't see anything with BOTH those sorts of things in the drawing).

There's nothing *you* are going to do to adjust a timer as it's a piece of software, not a mechanism.

If you want to know for sure that it is time based, you could disconnect the water line and listen to the water inlet valve and see when/if it "clicks open" and then "clicks closed" (with NO water flowing through it to trip a "float").

Does it throw an error code?

I searched on that web page for "float" and the search returned:

It does show part #531 on the drawings, "float". That wasn't hard at all.

How do you know that it's only for that purpose and not to detect normal water level, or maybe normal and too high conditions?

If it's anything like my coffee maker, there may be a water flow meter on the fill line rather than a timer. Then it wouldn't be dependent on water pressure.

Try:

I checked to make sure there was no flow meter as well. There is nothing on the fill line.

1. I don't think any manufacturer would want standing water outside and below the tub of the dishwasher.
2. By the time the dishwasher finished washing the pan would be full or overflowing.

The float switch in the diagram is outside the tub and below it? That doesn't make sense. How would it work like that? If you said that the float is positioned high so that water wouldn't normally trigger it, that would make sense and then I could see that it's only an overflow sensor.

The pan is supposed to be mostly full of water when it's running.

If it's like the float switch on every other DW I've owned, it is basically the reverse of the float switch on your sump pump. Hollow plastic tube/column extending up from the bottom, the top of which is above "flood level. Into this goes the float itself, a hollow cup with a long plastic stem dropping down through the column. Mounted outside the tub and below it is the switch which is controlled by the rise and fall of the float.

Overfilling is not normal operation. I suspect it is timer controlled (belt) with backup float (suspenders).

Belt and suspenders.

I had a bosch for a few years, nightmare/ when the warranty ran out i took it to te recycle scrap place

mine had a buried module that controlled all water levels.

cost a fortune, got clogged repeatedly. couldnt be disassembled and several hours ofhard work to replace.....

it failed twice, both requiring 2 techs to work on it together.

a real pos.......

And when I was looking it was - get this - the only "american manufactured" unit available
