My dishwasher runs for approx 3-4 hrs, even on Delicate/Econo mode. It sounds normal until the timer runs down to 1 min and then just runs for about 1-2 hrs and will eventually finish with "CL". The dishes are hot, but don't appear to be as clean as they should be. I can Cancel/Drain when I notice the "1" appearing with the same results. It appears that the dishwasher is still washing (?) during the "1". I recall the dishwasher being quiet during the heater drying cycle in the final minutes. Does this sound like a control module, heater or thermistor issue ?
Answer Hi Takman. First open the control board and see if you have 120 vac output from the control board to the heater. You need to do this while the unit is in a diagnostic mode. There should be a tech. sheet in the control board or the lower kick panel. If you do not have 120 vac out on the red wire at the board then gain access to the board and examine to see if there is a open solder joint on the board. You can use the door switch neutral for your meter black lead. Test the heater part # 00480317 for continuity while you are at the board.The control board is part # 00266746. Control Module - Made by Bosch. Common program control module for Bosch dishwashers SHU53/68. NOTE The manufacturer has redesigned the cover and indicator lights. Lights may be covered by the plastic case. You may have to remove the square covers over the indicator lights if needed. The same case is used for 6 and 8 indicator light models. They also no longer use the red bulb indicator lights, small surface mounted lights are used instead. Thank You.
My dishwasher has been making a loud noise when it empties for over 2 years now. It continued to clean fine until the last couple of times. Many of the dishes that would normally be clean were still dirty. Is the water no longer getting hot enough to clean properly? It is 11 years old. Is it worth repairing, and what part do I replace? Thank you.
Answer Hi Melia. You can at least try a couple of things. Remove power. Remove the racks and all wash arms. Use a pick tool to invert the wash arms in the sink and flush out completely with warm water. If the jet holes are plugged, cleaning is diminished greatly. Then. Use a shop vac, towels or paper towels to remove the top filter plate inside the top of the pump motor area. Set all parts very carefully aside as you know how to reassemble them. Clean all parts is the main issue. When you reach the chopper blade (stainless), you are pretty much all the way to the bottom. Check the sink to see if there is at least 120° incomming to the sink. Always run water hot while loading as to insure proper fresh fill. Adjust water heater as necessary. Use dishwasher magic monthly to insure proper performance. Part # TJ104. Start by doing these things. Let us know if we can assist further. Thank You.
What part of this model regulates the temperature of the water?
Answer Hello Missy. The water temperature is regulated with the heater assembly 00480317. This uses a thermistor 00165281 to read the temperature of the water. The assembly includes the thermistor. Hope this helps.
