Question about Bosch 24 in. SGS43C12 Classixx Free-Standing Dishwasher

1 Answer

Bosch classixx check water light

I have had this dishwasher for about 3-4 weeks. All working well, but today it stopped with about 119 minutes left (usually says around 142 mins). The "check water" light was on.
On opening dishwasher the bottom had dirty water in. Tried resetting to another cycle- nothing happening. Any ideas? hubby away a few days and would like not to feel a useless woman where machines are concerned and fix without having to call engineer. Extreemly useful (mechanically minded) teeenage daughter available to assist(with direction)!

    Same problem,but fixed as underneathe the filters at the bottom was a small cap that covers the top side of the pump impellar. This unclipped to show food stuck in the blades stopping the impellar rotating . Cleared the food and forgot to replace the cover ! so took the bottom off and found the discharge pump just rotates and unclips.Took off the dischrge pipe and blew through it to remove any blockages ( all when I needn't have) .

    Rememberd to refit the cover on testing and it started to pump out. :-)

    I have one question though.The discharge pipe goes from the pump up the side of the machine to what seems like a vent before going out to the drain .Whats the purpose of this vent if that what it is?

    Same problem, check water light on. Only had the dishwasher for 3-4 weeks, previous Bosch dishwasher went for years,no problems like this one....took the filters out, emptied sump and found the cover, removed cover sure enough impeller jammed with food? cleaned out and freed impeller awaiting the results, as the dishwasher is in cycle now. This new filter system looks the same as our old washer, but obviously lets bits through. Will now rinse our dishes before putting them through a wash cycle?? many thanks for the information

    I have tried starting a new cycle, nothing...what now?

    My bosch dishwasher does the same thing. Sometimes works after I shake it. I think there is a ball float somewhere that is stuck.Anyone know where it is?

Bosch classixx dishwasher starts cycle then says " check water" and then seems to do same thing again and again, pumping water in and draining it again

Probably jug impellor part number (424099) from espares, buyspares or bosch direct.
No fix unfortunately, this problem manifests as unit starts to fill and motor does not switch on. Eventually the unit overfills and the pump and fill start to alternate and check water light comes on. If this is the fault then this part is the solution it runs in line with the inlet valve and side fill chamber, take the left side panel off (looking from the front) it is tucked away behind the hoses bottom left (white plastic disc with two wire connection tag). Check water light can also come on if the unit is not pumping, if this is the case, repost and I will try and talk you through clearing this fault.

Bosch classixx dishwasher saying check water also not washing or spining

Bosch dishwashers have a food filter to catch food particles. You have to clean it occasionally, or it plugs up and stops water flow. This could be your problem. (Most other makers use a little grinding blade to finely chop the particles so they can be sent down the drain.)

Check water

very possibly you have a faulty water flow switch. If a certain flowrate is not detected within a certain time, that light would come on
