Replacing a thermostat on a dishwasher - Maytag MDB7100AWB Dishwasher

Based on the symptoms you described, it's likely that there is an issue with the heating element or thermostat in your Frigidaire dishwasher. Here are some troubleshooting steps you can try:

1. Check the heating element: The heating element is responsible for heating the water during the wash cycle and drying the dishes at the end of the cycle. If the element is faulty, the dishwasher may stop mid-cycle and display the flashing lights you described. Use a multimeter to test the continuity of the heating element. If there is no continuity, the heating element needs to be replaced.
2. Check the thermostat: The thermostat is a safety device that prevents the dishwasher from overheating. If the thermostat is faulty, it may shut off the heating element prematurely, causing the dishwasher to stop mid-cycle. Test the thermostat using a multimeter. If it's not functioning properly, it needs to be replaced.
3. Check the control board: If the heating element and thermostat are functioning properly, there may be an issue with the dishwasher's control board. A faulty control board can cause various issues, including the flashing lights you described. If this is the case, you may need to replace the control board.

If you're not comfortable performing these troubleshooting steps yourself, it's best to contact a qualified technician to diagnose and repair the issue.

A dishwasher that suddenly stops going through the cycles or never completely dry dishes probably has a faulty thermostat. The thermostat controls the heating elements for water and drying. If the thermostat is stuck, the dishwasher won't go to the next cycle because the minimum water temperature requirement is never met. Drying dishes also requires the temperature to get high enough to do the job.

1. Step 1 Remove the front plate of the dishwasher and locate the thermostat. If the thermostat is not located in the front of the unit pull the dishwasher out and remove the back access panel.
   
2. Step 2 Disconnect any wires or other parts that are in the way. Separate the wires with a flat blade screwdriver carefully to keep the wires from breaking.
   
3. Step 3 Take out the screws attaching the thermostat to the firewall and remove it from the dishwasher. Verify the replacement part matches the original, including the wire connector.
   
4. Step 4 Place the new thermostat into place and secure it with the screws. Connect the wires and replace any parts or cables. Attach the front or back plate and replace any molding.
   
5. Step 5 Run a hot water cycle and verify the water is heating and the cycle is able to complete. Check the drying cycle and prepare the first load of dishes.

It could be a malfunction heating element, thermostat or both. In most cases it's the heating element. Check with a multi-meter for 115/220V on the heater tags. In case you get this voltage there, you should replace the heating element. In case you can't read the 115/220V on the heater tags, check thermostat's for continuity (you should read a low resistance). In case you can't get any measurement. You should replace the thermostat. Good luck

Check with multi-meter for power on heating element's tags. If it does get power, you should replace the heating element. In case of no power- you should replace the thermostat. Good luck !
