SOURCE: 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.

SOURCE: Dishwasher not draining water

I had the same problem....removed hoses, checked for cloggs the hole nine yards.....Inside of the unit towards the back in the bottom is a filter cover and in the middle is a valve that you just screw out. It has a rubber stopper that overtime breaks down....I was able to pick up the part locally for about $17CDN, replaced the part and the unit drains properly now.....now I have an issue with no power

SOURCE: GE Potscrubber Dishwasher Model GSD

Hi and welcome to FixYa, I am Kelly.
There is and internal float switch that controls power to the inlet water valve. If the float is sensing that the unit is full of water it will go through all portions of the cycle but.... will not have any water in it at all.

Take a look at this diagram and check items 302 through 308:
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=209408&diagram_id=20816425#d20816425

The float should move up and down around 1/2 inch. I believe your float is stuck in the UP position. This is usually caused by food particulate on the stem (Item 306). Clean it up and it should work. You can gently push the stem up and down from under the unit and you should hear the micro-switch click as you raise and lower the stem. No click = bad micro-switch / no power to the inlet water valve. You can briefly jumper across the micro-switch to see if you get water flow during fill cycle. Just be aware of the dangers of working on live circuits.

Thanks for choosing FixYa,
Kelly

How I get to the drain pump to check if blocked on Bosh Logixx Variodrawer dishwasher please.

Pull the inlet hose off the drain pump to check for clogs. If this goes into a garbage disposal back flush the pump with a pressurized water source will also work. This means removing the unit from the house of course. Do you hear the drain pump running after a cycle completes?

Bosch dishwasher doesn't work. water not coming

Hi Gilgol, The link below is a Bosh Dishwasher list of error codes, I believe your error code is E3....CHEERS..
http://removeandreplace.com/2015/10/09/bosch-dishwasher-error-codes-how-to-clear-what-to-check/
Bosch Dishwasher Error Code E3
Fault Condition: Not filling with water
Repair or Check: If the water supply cut-off valve on the dishwasher is completely open but the dishwasher will not fill with water then shut off the water supply and unplug the dishwasher. Remove the water fill line and check to see if the water inlet screen valve is plugged up. If so then replace the water valve. Cleaning the screen can make the issue worse so always replace if the screen is clogged. The valve can get stuck open from gunk and therefore flood or overfill.

Dishwsher wont fill with water and beeps when turned out

It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/PUMP MOTOR/DRAIN to work when it is commanded .If this does not happen then the voltage at these points must be checked or the fault relates to no voltage/drive from the controller. This means the controller is a suspect.

Check how to remove the control panel: http://www.espares.co.uk/advice/dishwashers/a/3/1287/how-to-replace-a-hotpoint-dishwasher-fascia-p.html

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor. The water pressure must be good and the spraying must be seen to be good. If there is low pumping or pressure then the spray arms will not turn around to inject with pressure. If so the pump must be checked for clogging.

To replace check this link:

http://www.espares.co.uk/advice/dishwashers/a/3/1293/how-to-replace-the-spraying-system-on-a-dishw.html

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water.

Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

We have an L.G Dishwasher (Model: LD-2120-WH) and it is giving us a headache. It started right after we replaced the Sump assembly on it, now the drain motor starts draining when the Dishwasher is turned...

Please recheck the machine with the tips given here as I think the main program controller is activating the drain to work. So for the program to start up the main program controller must initiate the INLET valve to open up and allow water to flow into. If this does not happen then the voltage at the inlet valve must be checked or the fault relates to no voltage from the controller but if this activates the drain pump then it means the controller is a suspect.

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor .

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water .

Dd-602 water will not drain. Problem 2 U3 code started to beep

Hi

Thanks for using FixYa. Dishwasher not draining properly or not draining at all issues can arise due to different reasons. Usually, these issues are related to kinked hoses, knocked out disposer unit (if connected with the dishwasher drain hose) & clogged drain pump & filter.

Also note that dishwashers do not drain completely after a finished cycle and this is normal. Dishwashers are designed to leave some water in the unit to ensure that the heating element doesn’t overheat. If you suddenly begin to experience a large amount of water being retained in your dishwasher, you have a problem. Some of the most common reasons include that the drain hose isn’t working properly, the drain pump isn’t working correctly, or possibly there is a plumbing problem in your home’s drain lines.



First check whether the drain is not clogged or blocked and the line is not kinked. Check all the hoses for blockages & also clean the air gap. Has the disposer been replaced recently? If so, chances are the knockout is still in place. Simply remove the drain hose from the disposer, and knock out the plug. If the disposer has not been replaced, try removing the drain hose from the disposer and use a wet-dry vacuum (prepared for water, of course) to **** any water (and hopefully anything else) from the drain line. Then reconnect the hose, and test the unit. If you have checked the air gap and the drain hose and can’t locate the problem, then it is an issue with the drain pump of the dishwasher.

Please do rate the solution and revert for further assistance.

No water in washing/rinse cycle of dishwasher

It sounds as if the warter inlet valve (solinoid) isn't working and might have to be replaced. If everything else opeates fine, (unit pumps and sprays water that you added to it, pumps out and drains OK, then it is very likely the inlet valve has failed.

You can check for a blockage in the water inlet line, but unless you have a lot of sediment in your water or use a private well for your water supply, that would be a remote possibility, but worth taking a look at before buying replacement parts, etc.

You can remove the water supply hose/line and check for proper water flow and see if there is anything blocking the water from getting into the dishwasher. Many uints have a filter screen installed in them, so check that to see if it is blocked. Otherwise, look at the inlet valve and see if it is working correctly and go from there in replacing it.

One last thing, make sure the water supply line is actually providing water to the dishwasher, sometimes the water valves some installers use do get blocked, depending on how it was installed.
