SHY66CO5UC/14 Bosch drainage problems
« on: June 16, 2009, 08:56:28 PM »
One night suds starting coming out of my dishwasher and since then the dishwasher does not drain.  When I do a wash, the water just remains on the bottom and does not drain.  Rather than draining it just makes a humming noise.  I hate to spend hundreds of dollars to get it repaired.  Does anyone have any recommendations as to how I might fix it.

So you buy an expensive european made machine and now you "hate to spend hundreds of dollars on it"... I find that very ironic to say the least :)

Let's say you only spent about $67 on it, would that make you happier? That's the cost of the drain pump which is not working. The correct one for your model is shown below, and you can click the pic to order.

Drain pumps are mounted to sumps in the front of the dishwashers --they’re easily accessible from the front of dishwashers by removing toe kicks.To remove & install drain pump:

Tools needed: small flat blade screwdriver (for unlocking terminals).•Remove toe kick/base cover, pull up terminal cover and disconnect wires (using screwdriver to unlock locking terminals).•To remove pump, pull latch (on circular collar) & rotate pump clockwise (cw). To install new pump, insert @ 2:00 position & rotate counterclockwise (ccw). •Clean water & debris from base, then check float operation.•Connect wires, then install base cover & toe kick.

Did you mistakenly put dishwashing liquid in there in place of dishwasher detergent?
If so, repeatedly flush with COLD water until the suds lock is gone.

I removed the toe kick cover but there was another piece that was attached to the door.  How do I unscrew that piece?

Also, where would I put the cold water to try to unclog it?

Thanks to everyone.

The COLD water goes in the wash tub. Fill it to a normal level. Set the washer to run for a couple seconds, then hit the cancel drain. If it is a suds lock, you will have to do this several times to clear it.

I tried putting in the cold water; however, this did not work.  Can you think of anything else I might try.  Thank you.

You might try replacing the drain pump now...I can see you are one of those who could benefit from diagrams, so I am attaching the Service Manual.

The pump has a tab holding it to the sump housing. Use a skinny flat blade screwdriver to lift tghe tab and twist the pump housing off the sump, Get the glog out and turn the impeller to free it and snap that pump back into place. Nothing to it.
