My dishes all greasy and not dry, sanitize sensor stop work can u please help what I need to do?
Based on the description it sounds like the issue that you are having with the unit would be caused by a faulty heater circuit not allowing the water to get to proper temperature. Check the wiring in the door for broken or damaged wires. Check to make sure that the heater is getting power from the control board.
My bocsh dishwasher runs but the dish are not clean.
Answer Hi Sante. Without the model # all I can do is tell you to use dishwasher cleaner part # TJ104. Remove the lower rack and examine the wash arms to see if the jet holes are clogged. Remove them and use a pick tool to clear the debris. Rinse the wash arm upside down under sink water. Remove the pump top cover. Remove the parts internally one at a time and clean so you can reassemble them in order. As you get to the chopper blade at the bottom, you might have a broken or clogged blade. This is a common issue in all dishwashers. Thank You.
Dishwasher starts cycle and does not continue. All I hear is the motor running. Called Bosch and tried the reset, but did not work. Heater element is ok. I have the dishwasher pulled out and checked the filter and level switches and they are ok.
Answer Hi Timm. Per your description I presume it runs with water but does not heat. Then remove the front panel and look for the 2-large wires together on the board. Let it fill with hot water and verify incoming water at the sink is at least 120° while filling. Select heated dry. Then let the unit run for at least 10-15 minutes. Use a volt/ohm meter part # TJMA-DM1 to assist you in your diagnostics. Insert your red meter lead at the control board terminals and see if there is 120 vac output as the black meter lead will be on chassis ground. If there is no voltage output from the control board then stop operations and see if there is a open solder joint on back of the control board. If so then replace the control board part # 00186923. Then disconnect the wires from the board. Select ohms scale on your meter. Place the red meter lead into the wire connector itself and test for ohms as the black meter lead is on ground as well. If there is resistance then the thermal fuse and the heater part # 00480317 circuit is good. Along with the wire circuit connections as well. If not then you access each component itself and with the wires disconnected, ohm each component. The thermal fuse needs to be closed -0 ohms. If open (infinity) replace it. The heater should read 11 ohms =/-10% tolerance. Make sure to test the heater ohms to ground as well for a short (0-ohms). Thank You.
If I replace the circulation pump, do I need to replace the heater?
Answer Hello Tony,
The heater 00480317 is an electronic component that is really put through the paces, but I still cannot advise to replace a good part. If you test the heater and it tests bad, certainly replace it at that time.
