  William RichardsAug 20, 2025
  If your Midea Dishwasher is leaking water, several factors could be responsible. There may be too much water fill. The tub seal, softener gasket, or drain pump could be defective and need replacement. Ensure the dishwasher is level. Check for loose hose clamps and tighten or replace them. Inspect the heater element for looseness and tighten the mounting nuts. Also, check the sump seals and replace if defective. Make sure the motor and drain pump assembly are properly seated with the sump, and the heater elements support assembly seals are correctly mounted.

Why is there water remaining in the bottom of my Midea WQP6-3207A Dishwasher?
- M
  Melissa BowersAug 27, 2025
  A small amount of water in the sump area of your Midea Dishwasher is normal to keep the pump primed; it drains automatically at the beginning of each cycle. However, if there's excessive water, it could be due to a defective drain pump, check plate, or one-way valve, which may need cleaning or replacement.

Why is my Midea Dishwasher not filling with water properly?
- J
  Jennifer PachecoAug 28, 2025
  Your Midea Dishwasher may not be filling with water properly due to several reasons. The water supply might be turned off, so ensure it is on. There could be low water pressure (minimum 20 PSI required). The water fill valve or hose may be obstructed, requiring disassembly and cleaning. Other potential causes include a defective water fill valve, a damaged or defective wiring, a defective pressure switch, a defective flowmeter, heavy water usage elsewhere in your home, or a defective PCB assembly. Also, try to use the dishwasher when water usage is at a minimum.

Why does my Midea WQP6-3207A run, but not heat the water?
- B
  Brian GomezAug 30, 2025
  If your Midea Dishwasher runs but doesn't heat, check if the input voltage is at least 198V. Other possible causes include a defective thermal resistor, defective wiring, too little water fill, a defective micro-switch of the heater elements support assembly, a defective heater element, or a defective PCB assembly. If there is too little water fill, refer to the section addressing that issue.
