Question about Bosch Dishwashers
I have a Bosch Ascenta dishwasher model SHE4AM16uc. It seems to get stuck in cycle. What happens is that it won't stop filling. It just keeps filling and the overfill float activates the pump which drains it down untill the pump stops but the fill water keeps coming in so this cycle is repeated over and over. I ran a test cycle to clear the codes and I thought the problem was solved but it is back to doing it again. I made sure the sump pit was water free on start and I made sure the microfilter was completely free of debris. If I turn off the water supply, the cycle will advance otherwise it will just keep filling and pumping. The repair manual advises that the fill system is on a timer rather than an impeller jug. Any suggestions would be very much appreciated! Thanks!

OK Bosch Dw fans.........here is the fix if your SHX dishwasher is stuck on the drain cycle. This may save you a couple hundred bucks.......so listen up. There is a tendency for the very small float switch to STICK in the ON position, which will cause the drain motor to continuously run......and DISallow any other function to work. DISCONNECT POWER. Did I mention to disconnect power? Take off the front base cover....2 torx screws. Remove the other 2 torx screws in the metal clips that fasten the top of the DW to the underside of your countertop. NOW...carefull slide your DW out. You may have to disconnect your water and elec supply if you do not have enough slack to pull it out. Once the DW is out of the cabinet, remove the shiny metal cover on the LEFT side by removing a single torx screw. You will now see a small plastic assembly with a red plastic piece that moves up and down as it rides on a small red styrofoam float. This up and down movement engages a small white plastic switch visible with 3 wires coming out of it. You can carefully UNSNAP this switch out of its mount, and pull the 3 wire plug off of it. THere is a small square blue plastic tab that is supposed to easily slide in and out of the switch. If it is stuck IN, you can sometimes tap the switch and the blue tab will pop out, which is what it is supposed to do without tapping it. You can carefully with a knife blade separate the case on this switch and note the way it comes apart. Clean out any micro debris out of the small channels that the blue tab ride up and down in. Then set it in the channel while holding up the small switch tab that rides on it and see if it slides up and down without sticking! I like to take a piece of wax paper and rub in on the channel and blue tap to provide some lube for the switch to slide easily on. Now, put the switch back on and manually move the red plastic assembly up and down while you are watching the blue tab. The tab should ride up and down with the red assy. If not, buy a new switch. Google the # on the switch and order one. If the tab slides up and down, put things together in reverse order and give it a try. Hope it works for you. This should take you an hour give or take. Take the $200 you just saved and have a night out on me. ........so even though these German Appliances have a good name because of past reliability, the american tendency to value engineer them with plastic parts to reduce costs and increase profit.........just cost you an hour of your time. Will we ever learn.? ......if it ain't broke, value engineer it until it only lasts through the warranty period so you can then collect service and parts blood money from your fellow american.

pull the dishwasher out and look inside the pan you more than likley have a leak and this is why it is not filling it has a safety so when it leak it will not fill with any more water.

Thanks for using FixYa. If the clean light flashes, pauses, and then repeats. When the dishwasher doesn't sense a water temperature increase, it stops working and locks the functions (clean light flashes, all buttons are non responsive). It does this as a safety in case the element is broken and feeding electrical current into the water.
To resolve this you will have to reset the console. Do this by closing the door and press these buttons in sequence...
-high temp wash
-high temp wash
All the lights will turn on briefly and the machine will start a diagnostic cycle. You can press cancel or let the diagnostic cycle finish (1-2 minutes). You should now be able to run the dishwasher as normal. If the issue returns, you could have a problem with the heating circuit (i.e. element, thermostat or wiring). It rarely happens but it could also be the door switch not engaging properly when the door is closed (slightly bend the door latch down making sure it doesn't hit the door when you close it).
Please do accept the solution if the issue is resolved or else revert for further assistance.
