Gaggenau dishwasher is not draining

It is possible that the machine does not start off the cycle because there are errors or feedback from the inputs. For the program to start up the main program controller must initiate the INLET/PUMP MOTOR/DRAIN to work when it is commanded .If this does not happen then the voltage at these points must be checked or the fault relates to no voltage/drive from the controller. This means the controller is a suspect.

Check how to remove the control panel: http://www.espares.co.uk/advice/dishwashers/a/3/1287/how-to-replace-a-hotpoint-dishwasher-fascia-p.html

If the water flows then the flow should be good, if not the inlet valve is bad or there is dirt in the filter. Also check the flow at the inlet of the water line. What is most important for the motor to start functioning is that the door switch must be ON when the door is shut or this will be an error for starting the motor. The water pressure must be good and the spraying must be seen to be good. If there is low pumping or pressure then the spray arms will not turn around to inject with pressure. If so the pump must be checked for clogging.

Finally after the wash the drain valve will be activated, the water is allowed to come in to rinse and then finally the drain valve/pump activated so as to drain off all the water.

Make sure that a fault in any of the cycle will relate to the specified action, so check the command from the program module and then the executing device be it the valve or motor or pump.

First perform a vinegar cycle wash in the dishwasher. Pour a cup of vinegar into the bottom of the dishwasher. Keep the temperature at the highest setting possible and perform a wash cycle.Then start using a dishwasher most probably that would solve the problem. If this does not solve the problem then there must be some parts worn out or faulty creating the problem.

There are many probable causes of failure .

To clean the dishes the water temperature is essential.It the water is not hot then the dishes will not be cleaned properly.So check the water temperature.

Also check the filter in your dishwasher.Clean the filter if there is accumulation of debris in the filter

Hello, welcome to FixYa.

The dishwasher you're speaking of (provided it is indeed a Gaggenau GM954) is built by Bosch as you may or may not know.

To address your concern regarding the 2H in the display actually needs to be done in two parts. I'll start with the basic info associated with the 2H displayed.

This can be simply indicating the previous cycle exceeded a 2 hour wash cycle, not necessarily an error and can be attributed with too cold water entering the dishwasher (below the recommended 120F), a longer than normal drain time (due to partial blockages, kink etc. hence longer time needed to complete the cycle) or inproper water circulation during the cycle.

Aside from these issues, it (2H) can also mean the unit has a heating error and if left long enough will show another error of "1" in the display, extremely long wash times, etc.

**The first thing I'd suggest before attempting any repair is running an additional cycle while making sure the water inlet is hot (120F optimum) and the unit does indeed drain fine.

**A fair indication of proper draining is to start a cycle and once washing begins (2-3 minutes) activate the "cancel" and the unit should adequately drain in the 2 minute time allowance.

**To identify proper water circulation, place an empty cup in the upright position in the top rack, start a cycle and inspect the cup after 2-3 minutes and it should be full of water.

After trying and posting the results of these thing's we can move forward with potential heating errors, the cause, and how to remedy them. Let me know what you find and I'll continue to assist you in any manner possible going forward. Good luck.

After the intital cycle of the water inlet vavle opening the program shifts to the next mode But since there is errors on the controller the machine shuts off with an alarm.
Now check the front door opening switches, check the washer pumps, check the drain cycle/pump.
remove and check the door switch contacts, the pump and the drain.

Hello, welcome to FixYa. While I don't have access to my PC files at the moment as I am on my iphone, I believe this is the procedure for most B/S/H/ built dishwashers ( that means Bosch, Thermador, Siemens and Gaggenau ). To Enable or Disable the Cycle Completion Signal... 1. Open the door, hold down the ?Quick Wash? button and simultaneously turn the Dishwasher on. The ?Quick Wash? light will blink (program mode). 2. While the light is still blinking, push the ?Quick Wash? button. ? If the machine beeps, then the Cycle Completion Signal has been enabled. ? When you push the button again and it doesn?t beep, it means that the Cycle Completion Signal has been disabled. 3. Turn the Dishwasher off to take it out of program mode. I hope this answer's your question. Thank you for choosing "fixya". Please rate the solution favorably if indeed it was helpful, if not please let me know. Good luck. macmarkus :)

Dishwasher Problems - Water will not drain out

most washing machines nowadays have a electrically operated switch that will open to either drain or let in water if ur machine does not drain the water the machine will not go ahead in completing its cycle as the sensors sense that there is water in the drum so unless the water drains u will have this problem. Check for a click sound when the machine reaches a point to drain if that doesn't happen then it is this drain switch that isn't working

Does it show a fault code? eg F4?

It could be cause the water level switch. The level switch is usually a diaphragm device with a small clear tube attached between the switch and the bottom of the washer's outer tub. I am not familiar with your machine,but if you will open the rear panel you will find it easily. Clear tube from any obstruction. Good luck !
