I don't think there is a solenoid, its a drain pump.. don't know if you have a draining problem, but try taking the d/w drain line off your sink drain line and check to see if the water will drain out. you can use a wet vac to clear out drain line.. also, if you have a new garbage disposal under sink make sure the side drain area for dishwasher is punch out. Hope this will help...

Dishwasher doesn't drain completly, I took off drain hose to see if it was plugged. Any other ideas?


Hello, welcome to FixYa.
I understand by reading your post which indicates it is a dishwasher you appear to have a drain cycle concern, however if you could verify the make, i.e. Kenmore, Bosch, Whirlpool etc. And post the model number I'd be better equipped to help without generalizing.
I'll watch for your reply and try and help going forward. Thank you.
Regards,
Macmarkus :)

The dishwasher doesn't complete the cycle and switches off without draining.


Try advancing the timer manually. It could be that your timer is sticking.

My bosch shu43co5 made a burning smell and stop working in middal of a wash the breaker seems to be fine and trying the power button/ powerscub/ reg wash don't get any lights on. what is my next step in...


Hello,

Welcome to FixYa.

**Before I begin I will inform you B/S/H/ ( Bosch Thermador, Gaggenau ) issued a recall on certain models between 1999 - 2006 depending on the serial number.** Here's the link so you can see for yourself.

http://microsites.boschappliances.com/safetyrecall/dishwasher/

Aside from that and based on your post "my bosch shu43co5 made a burning smell and stop working in middle of a wash the breaker seems to be fine" it may just be a loose/burnt connection in the dishwasher junction box.

**Now I would start by first shutting off the breaker...safety first**

Then removing the kick plate ( access panel at the bottom )...

...and checking the wiring at the junction box for the dishwasher 120vac supply line.

Remove the murret's and visually inspect the wire for "resistance burn" and strip the wires back and install new fastener's if necessary to repair.

i.e.

60f6a31.jpg

This is actually quite common to find a wire connector come loose due to improper fastening and once the unit is in use for a while the connections heat & cool, become loose from normal operating vibrations and burn up from all the added heat caused by "resistance".

Typically this will manifest in just the manner you've described.


Let me know what you find and I'll try to assist you further if necessary. I'd still suggest looking into the possible recall for your machine though.

Regards,

Macmarkus :)

Dishwasher won't drain


Hi

Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. Check the drain hose for any visible clogging, remove if present. If no visible lint is present then remove then turn off the dishwasher and remove the drain hose and check for any visible clogging. If still not visible then the drain filter or drain pump is clogged and you’ll need to clean the drain filter and drain pump.

Please note that dishwashers don’t drain out the complete water such that heating element doesn’t overheat.

Please post back for any further assistance.

My bosch excell dishwasher won't drain it stops during the wash and won't restart until I have emptied the water then it will wash ok until it gets to the drain part of the programme then it stops again....


A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.

Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.

Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.

Water not draining


If the water doesn't drain from your dishwasher, check these:
  1. Drain line/air gap--A clog in this part is the usual reason that a dishwasher doesn't drain. Remove the drain line to clear any debris from the hose or hose connection at the household drain line connection. Reattach the hose before starting the dishwasher again.
  2. Pump--You can reach the pump from inside the dishwasher. Remove the lower rack, spray arm and support. Look for an impeller, a device that spins around and forces water through the spray arm. This is the wash impeller and beneath it is the drain impeller that pushes the water into the drain port. Replace it if found defective or worn out.
  3. Drain valve/solenoid---The drain valve may have a solenoid with lever that sticks or frozen and prevents the dishwasher from draining. Free up the solenoid and lubricate the lever.
  4. Belt---A certain brand of dishwasher uses a belt to drive the pump. Replace it if broken or worn out.
  5. Motor---Check it if turning or working.Turn the rotor manually to see if stuck and free it up. Replace if defective, it is not serviceable.

Bosch smu2046uc doesn't drain completely (water sits in the very bottom of the drain) and mildew builds up inside the dishwasher quickly--makes dishes dirty. How do I solve?


check the following parts for their operational value. replace any failed part.


1. Air gap / Drain hoses
If there is an air gap (located in the sink, near the faucet), check to see if it is clogged. Unscrew the top cap and see if there is anything blocking inside. Note: If there is no air gap installed, the dishwasher might not drain properly.

If the drain hose is clogged, the dishwasher would not drain. If there is an air gap installed, it is very common that a hose going from the air gap into the garbage disposer is clogged. Remove and clean the hose. Make sure to reattach the hose before starting the dishwasher.

Note: If you recently had a garbage disposer installed, it is common to overlook removing the drain plug.

2. Broken belt
Some dishwasher models use a belt to drive the pump. Replace the belt if found broken.

Note: Sometimes the belt would just come off the pump. Even though it might not be broken, it is recommended that you replace the belt, because it is probably too stretched out.

3. Pump
Some models have two impellers inside the pump - one, wash impeller, takes care of the wash cycles, the other, drain impeller, drains the water out. If the drain impeller is broken (broken blades, shaft), the dishwasher would not drain. Replace any broken pump components.

4. Drain solenoid
Some models (for example most GE dishwashers) use a drain solenoid to drain water out. Sometimes the solenoid gets stuck, preventing the water from draining out. Try to free up the solenoid. If unsuccessful, you might have to replace the pump assembly.

5. Motor
If the motor is stuck, it is sometimes possible to free it up by manually spinning the motor.

Replace the motor if defective.

6. Timer
Replace if defective (note: uncommon problem).

Bosch dishwasher has water in bottom after cycle is complete


Hi

Kindly check for the following :

Check for hose kinks or food plugging drain hose. Start at the drain port exit.
Check the check valve and drain hose for debris.
Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle.
Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise
If you have recently installed a new garbage disposal, check knock-out plug at connection.

Check pump impeller for damage.
Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.

Please contact for any further clarifications.

A Fixya Rating would be appreciated if.

Thanks

Dishwasher draining - Bosch SGV4313GB/17


This is generally because of a stuck diverter solenoid. The water goes to the pump and then is either sent to the wash arms or the drain. Also, check the drain.
