Mike I for Model Number BOSCHE SHX36L05UC

Answer Hello Mike. The heater 480317 should read closed for continuity when tested. 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

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. 

Lone Star for Model Number DW44ZS/12

Answer Hello, This is the only heater 480317 in the unit and it is used to raise the interior temperature to cause the evaporation which dries the dishes.

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 # 186923. 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 # 480317 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.

Answer Hello Tony, The heater 480317 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. 

Lee for Model Number SHU 4302 UC/11 FD8004

Answer Hi Lee. The wash light lit up means that the ntc circuit needs replaced. Part # 480317. This is an upgraded part design from the manufacture to keep this from happening again. Thank you for the nice comment we try, I wish I could tell you this will be a breeze, but that's not the case on this one my friend, My best advice to you on this one is to remove the unit from the counter, and lay it on its back, that is the only way you will gain access to the AP2802450 just take your time and be careful be sure to turn power off before you start, you will see the assembly,and you will have to remove the bottom to get to it , also be sure you tighten up all the clamps when you put the new one on ,I forgot one of them one time the customer was talking to me and I forgot one pay attention or you will to . Thank you and good luck !
