Bosch SHU9925UC Dishwasher Stuck in Initial Drain Cycle

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.

Clogged Bosch SHU 9920 dishwasher

-Sounds like the pump is not working properly or the drain line you connect to sink directly instead to the breath cap before to the sink. Or the breath cap locate too low. -Make sure the breath cap is mount higher than the line to the sink. (Or as high as possible) This is to prevent any water from the sink pour into the dishwasher. Good luck Mai

I have a Bosch dishwasher,

green wires are usually earth wire where is the wire going to? also the water valve is not really the problem, if its not turning on water but doing the rest, it will be the relay on the main pcb board these can fail, they run on a 12v supply and send power to the valve to open 12v opens the switch so the mains voltage can turn on the valve at the right times. the switches are common to fail as they can arc over time and lock closed so cannot connect again. if you know how to solder you can remove the old one and replace with a new one you can buy these relays on ebay or other electronic stores there are many types on the one you have is a part number buy the same part. to locate the right relay as there are meany use a meter and connect one end to the positive wire on the vale and the other end to a random relay on the pcb checking them all till you get a reading or beep depending on what settings you use, then change that one for new one.

Bosch SMS 4012. Water very slow to enter machine

The solenoid valves do gum up. Replace that and it should work fine. They are not very expensive. You could try to clean it, but it is easier to just replace it.

My bosch dishwasher is not


Welcome to FixYa.

Based on your description, " my bosch dishwasher is not filling up with water. Where is the inlet filter? "... and to answer your question, the issue is likely with the inlet/water valve.

**To remedy this you will need to replace the valve, not surprising for Bosch unfortunately**

This is what to look for..i.e.


As long as your model number is indeed SHU8805 series, this info below will be accurate.

Original part is # 425458. It usually retails for about $20 - $30USD at places such as "searspartsdirect.com" "repairclinic.com" to name a couple.

**Before attempting to repair the unit please turn off the power and the water supply to the dishwasher...safety first**

If you remove the lower kick plate/toe panel, you will see the inlet valve to your left...



Replacing it or to check for debris in the filter/screen at the inlet is pretty straight forward. Here`s how...

1) undo the water line. ( here you can visually inspect the screen in the valve...if nothing noted, you'll likely need to replace it as follows )

2) Remove the two #20 torx screws fastening it in place.


3) the feed tube to the machine at the back of the valve and swap it with the new one.


Once the new one is in you should be good to go.

Let me know if you need any further assistance, otherwise good luck.

Thanks for visiting FixYa.
