Chosen Solution
I have an issue with a Kenmore model- 665.13003n511 (seems like an awfully long model number). It does not heat up very well. I have already replaced the heating element (This part was actually bad, and was starting to get some corrosion on it), and it is still not cleaning or drying well. I do use a drying agent with it. Does anyone have any ideas on how I can fix this, or where I can start next? TIA!
Hi @imbob218 , Check that the dishwasher’s hot water supply is 120 deg. F (49 deg. C) at the dishwasher. (see p.6 of the installation manual) The heater element only raises the temperature by some 40 deg. F maximum (see p.16 of the user manual for the different temperatures used by the different wash cycles). If the supply is not hot enough then the heater may not be able to bring it up to the required temperature. Update (03/07/2021) Hi @imbob218 According to this supplier the manufacturer’s part number for the tech sheet is Tech Sheet - W10849767 - Rev A. Scroll down to p.5 and find the Water Heating/Heat Dry and Water Sensing with O.W.I. Sensor (Water/Air/Soil/Temperature) circuit. On p.6-7 it shows how to get into the Diagnostics, what the error codes mean if any shown and what to look for, for each error code. Hopefully between using the two you will find the problem
Thermostat The thermostat is the other component that can commonly cause your dishwasher to not heat the water. The job of the thermostat is to regulate the water temperature throughout a wash program. If it’s faulty then the dishwasher won’t “know” when to turn the heating element on and off to keep the water at the required temperature. Just like the heating element, you can test the thermostat using a multimeter to determine whether or not it is the source of the fault. Luckily it’s a very cheap part if you need to replace it, the only real difficulty is getting access to it as you’ll find it underneath the dishwasher.
