Cycle runs normally but water doesn't drain out.
Answer Hello Kathy. Check and make sure nothing is clogged. If not, you will need to see if there is power coming to the drain pump. If so, you will need to order and replace the drain pump on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
I just replaced the water fill valve - BSH 00425458 (as suggested in your previous response to my problem) and the machine still displays a "1" at the end and never shuts off. Any other thoughts?
Answer Hello Steve,
If the water valve was at fault there will be some water in the base of the unit and the flood switch will be activated. This basically tells the control there is a water leak and all the unit will do is try to drain until the water in the base is emptied. I always use the corner of a towel that has not been washed with fabric softener, (since the softener will repel water instead of soaking it up). The easiest way to clear this water is by removing the water valve and fishing the towel into the bottom of the base through this opening. Be careful not to damage the Styrofoam float in the bottom. When the water in the base is removed the unit should resume normal operation.
The dishwasher runs and washes normally but continues running while displaying a "1". I replaced the Heater relay to no avail. Followed a procedure to measure resistance on the Aqua Sensor and find it reads less than 1ohm. The Manual indicates that it should read about 1 Meg ohm. Pulled the sensor and got the same resistance. Do you think that is causing the continuous running and display of "1" or do I have problems. All other resistance measurements seem to be ok.
Answer Hello Steve,
This is normally cause by a water valve not opening all the way which in turn causes the water to drizzle out of a port hole into the main base, floating the flood switch. This causes the drain pump to run constantly and in some cases, (depending o the wiring configuration), even with the door opened. Removing the kick panel and moving the red flood switch activating rod will turn it off. Water will be standing in the main base if this is the issue. This water has to be removed with a towel or shop vac, (be careful not to damage the styrofaom float). Replacing the water valve 00425458 and removing the standing water in the main base corrects the issue.
The dishwasher works but the timer goes to 1 and stays till you turn off. Replaced the control module and still goes to 1 and stays. Upon running diagnostics I get a 3 which is aqua sensor and heating fault. Water did seem to get hot though and sometimes the tablet would not fall out.
You will need to check under the unit and check to make sure that there is no water in the base plate. If there is then this would be the cause. If water is in the baseplate then the flood switch is seeing this and causing the drain to continue to run until the water is sensed not being there.
I have a Bosch model 8806.
At first I would find the deterent tablet on the bottom of dishwasher never dissoved. Now the dishwasher doesn't even start when you turn it on.
What is the problem?
You will want to check to make sure that there is power getting to the control board. If the Control board has power going into it and the door switches are good then you would need a new control unit.
