Question about Bosch 24 in. SHU66C02 / SHU66C06 Built-in Dishwasher

1 Answer

My SHE43 Bosch DW will not pump the water out after the last cycle. The service guy said the Door latch was broken and replaced it. but the problem still exist. He now say that the water lines are freezing up because the DW is on an outside wall. The Thermador DW that was replaced never had this problem during the 15 years it was located in the same place. Could this be a bad design? Help!!!

    When it very cold it stops working . Could the lines be freezing? The service guy says that is the problem. The Thermador that was there before never had rhis problem. Comments?

    We have the same problem. Our pump will start, then stop. The repairman who visited today thinks it is the electronic board and it looks like it may be under a recall. He's checking into it for us.

I  the water doesn't drain from your dishwasher, check these:

Drain line/air gap
Pump
Drain valve and/or solenoid
Belt
Motor
Timer
Drain line/air gap 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.

Pump Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support. 

Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

Drain valve and/or solenoid 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.

Belt One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.

Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced. 

Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.

Timer Part of what the timer does is control the motor and drain valve. If the timer doesn't work properly, the water may not drain and you need to replace the timer. This problem is uncommon.

HI,

If your dishwasher leaks, check these:

Main tub seal
Door gasket or seal
Water-inlet valve
Hoses
Main tub seal Note… If the main motor of your dishwasher is mounted vertically, beneath the center bottom of the dishwasher, the following instructions probably apply to you. But if your motor is mounted horizontally, the pump isn't serviceable--you need to replace the entire pump and motor assembly.

The main tub seal is beneath the drain impeller. It prevents the water in the dishwasher from leaking out near the shaft of the motor. To get to the seal, which is inside the dishwasher, remove the:

  • Lower rack


  • Spray arm


  • Spray arm support


  • Wash/drain impellers


Then pry the seal out of its housing and replace it.

Door gasket or seal Over time, door gaskets and seals harden and lose their ability to seal properly. You can't repair the seals. You need to replace them if they've begun to leak.

Water-inlet valve The water-inlet valve, itself, seldom leaks. But, the water-supply line from the house and the rubber tube leading from the valve to the inside of the dishwasher may leak. Tighten or repair/replace these as necessary.

The water-inlet valve could mechanically stick open. When that happens, the water continues to flow into the dishwasher, which then floods your kitchen. Turn off the water supply to the dishwasher, and replace the valve.

Hoses Behind the lower access panel on your dishwasher are several rubber or plastic hoses. If the leak appears at a connection, try a new clamp. If that doesn't work, replace the hose.

9-14-14 How do I increase dishwasher pump drain pressure?


Wow, you've really tried hard to fix this problem (and describe what you've tried to do to fix it). But for me to be able to fix it, I need to know the model number, and approximately how old the dishwasher is. Does this model use a separate drain motor, or does it have just one motor and a diverter powered by a solenoid to drain the water?

Bosch SHX46A (6 years old) Selected regular cycle, pressed On and closed door. Cycle did not start normally. Pump runs, but no water is coming into the DW. I confirmed the water supply line is turned on....


From your description, I doubt that the problem is door latch is the cause.
The first thing that a modern dishwasher does before it begins to fill with water is run the drain pump.  It appears that this DW is not progressing to the next cycle (inlet water) and because the pump runs even when the door is open, I agree that the controller card may have failed.
If possible, inspect all the wire connections (remove main power before you do this) ... if there is a loose connection, the controller could do odd things.
Good Luck!  Please report back what you find, OK?

Water leaking onto the floor


1. If the water is going onto the floor during the drain cycle there is either a hole in the hose or it is completely loose from the DW or a hole in the drain assembly under the sink but if that were the case you would have water under the sink also.
2. If it during the wash or rinse cycle then the seals are not sealing (door is not closed all the way or seals are bad) or the float at the right front of the DW is stuck allowing the DW to overfill with water.(you need to open the door and pull the float up and out as you do so push it up and down and listen for a clicking sound.(which indicates it is making contact with the fill solenoid)..if you here the clicking and the float is full of gunk (old soap and such) clean it out and replace it and run it through a cycle and monitor the DW to see if the fill cycle shuts off before the water reaches the overflow point.
3. the only other option is a possible rust through on the DW and or the drain and motor mount in the center of the DW where the food particles and water are drained...is loose and leaking or rusted through...(how old is the DW).
4. Also check to see there are no large particles around the door seal to prevent complete closure and sealing of the door seal. As well as the door latching properly (when closed can the door be moved or pulled open)?

I hope this helps and let me know if not Please relay model number, age and other specifics you feel are pertinent...thank you and please rate me if this helped...thanks again ...the Fang

Dish washer that does not pump out the water on it"s final cycle


I had this same problem and after having the repairman over to our house several times and having the circuit board changed, I figured it out on my own...

It turns out that the pressure created from the steam during the water heating stage (HO) was pushing on the door latch just enough to prevent the motor from running properly. Because the door wasn't latched completely, the water wouldn't drain and the dishwasher would go to the "Drying" cycle without ever pumping the water out of the basin.

I adjusted the levelling on the DW and that helped, but I'm still not sure that the problem is fixed. We may need a new latch assembly.

To test this, when the DW stops running at any time, push on the door. If the motor kicks back on, this is the problem.

Bosch dishwashers have a seperate pump for washing and another for draining. Try making it fill more than once. There is usually a timed fill and the float stops it before it overfills It also might prevent it from washing without enouth water Try defeating the door switch and play with the float during fill. There may be a sensor that won't let it go into wash. Be prepared to get a little wet if it should start up suddenly. A slightly safer way is to fill it with the sprayer from the sink. and see if it will go into wash.
