SOURCE: Bosch Dishwasher won't drain, cancel drain lights blink

I had a similar problem and called out an engineer. When he ran it on rinse it worked fine. Said the micro chip had got confused because I kept pressing buttons. Worked fine for a few weeks and has started playing up again. I have reset it again and hope for the best!

SOURCE: Bosch SHU43CO2UC/22 will not drain

I had the same problem on Christmas Eve. It turned out that the impeller blade was blocked by a grain of uncooked rice which had found its way through the filters in the bottom of the dishwasher.

The impeller pumps the water out of the machine and is separate to the pump which sends water out of the spray arms.

If you have the user manual for the dishwasher, you will find instructions and a diagram of the parts in the troubleshooting section, but it is fairly straightforward.

To get to the impeller, remove the food filter from the bottom of the dishwasher (it simply lifts out) and then you will be able to lift out the metal filter grid and pull it out towards the front.

This will expose the plastic outlet where the impeller is housed. To reach the impeller, undo the cover which is held on with 2 torx screws, and you will be able to see the impeller blades. Try turning the blades, they should move without any resistance. If they are stuck, try using tweezers to find and remove the obstruction so that the blades move freely (there will be some slight resistance from the magnets around the impeller, but the blades should move easily).

That solved my problem, and I was able to spend Christmas Day without washing up by hand! I hope that it works for you.

SOURCE: Bosch SHU9925UC Dishwasher Stuck in Initial Drain Cycle

OK Bosch Dw is the fix if your SHX dishwasher is stuck on the drain cycle. This may save you a couple hundred 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. 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.

Hi i have a SIMPSON ESPRIT 600 TOP LOADER WASHING MACHINE. The wash cycle works fine however during the drain and spin cycle, the water wont drain. The machine makes a noise during the drain cycle but...

My guess would be replace the pump, it is normally driven by the motor and if the wash cycle is good the motor is operational. You have to investigate to find the actual part to replace.

How do i fix the E-13 error on my washing machine?

Hi Jerry,
I had a similar problem my LG would sometimes wash and other times I received a code(forgot the code it's been awhile)it wouldn't drain, I changed the pump etc.. I had the repairman at the house three times finally PC Richards replaced the washing machine. However after a week the same code came up. I and checked the voltage at the outlet and it read good. So, I checked the voltage while machine was running and I had 89V. I had a bad circuit breaker changed breaker problem solved! I hope this helps.

This maybe due to a clogged drain hose, sometimes food will clog the drain valve causing the unit not to drain the water. Check the drain plug for clogged debris in it.

Hi just read your posting.As I understand from your posting the machine will not drain and you want to check the drain pump motor and not the main drive motor,Is this correct?If you want to check the drain pump, 1st drain some of the water by hand , enough so you can look under the machine without the water spilling everywhere.When you are under the machine look to the front right and you should see a red or black fan.This is your pump.Turn the fan clockwise and anticlockwise a few times to hopefully unjam the pump.The fan should turn freely.If the fan turns freely put the machine back upright and start a spin cycle.Hopefully the machine starts to drain.Please reply on how you got on or if you have the other style of pump or if the machine stills does not drain.Looking forward to your reply.

Won't spin, just agitates. Clothes and water still in machine !!

Glad to hear of progress.Pump could be faulty. 1st you need to check nothing is stuck in the pump ie..coin, next make sure the filter is clean, now is the pump blade free to turn by hand if not investigate why. If all okay replace pump if satisfied there is no blockage and water is flowing to the pump,worthwhile at the final stage to make sure final drain hose to waste pipe is clear..Good luck if I can help anymore please ask...

The washer want drain

Hi, the problem is either your pump or your hoses. this an easy fix. all you need is a screwdriver and a bucket to catch water. 1st unplug the machine and remove the drain hose from the drain. then try to drain the water from the washer by plugging it back in and setting the washer to drain. if no water comes out of your drain hose then you know your plumbing is ok. next put the drain hose back in the drain and take the cabinet of your washer. you will see your pump with 2 hoses connecting to it. one hose connects to the basket and the other to the drain. disconnect the hose coming from the basket and if water comes out then you know the basket is not blocked with any article of clothing. if both check out ok your problem would be the pump. write down the model and serial number to your washer and buy a pump. Thanks! mannu_rakesh

How many pumps in washer gwl-11 F&P?

It's the same pump but, the click you hear between cycles is a solenoid switching between hoses. Chances are-you have a buildup of debris at the inlet of the pump. I've removed baby socks from them already.

Will not Drain

when the machine is full of water detach the waste pipe from wherever it is connected i.e under the sink or some other type of drainage ..

Lay the pipe on the floor (ground level ) if the water comes out then their is no blockage and you need a new drain pump.

easy to change with the slightest of mechanical knowlegde
