DIY – How To Fix Dishwasher Leaking Problem

How to fix dishwasher leaking problem

Does your dishwasher leak during the wash cycle or after washing? The water leak may be caused by a problem internal or external to the device. Is your dishwasher leaking under the machine or through the door? If the draining is not carried out correctly, the machine may be clogged. How to unclog a dishwasher? Is the water inlet, drain or drain hose pierced? Are the seals involved? The circulation pump, the solenoid valve, the pressure switch or motor are they down? Follow our tips on how to fix the dishwasher leaking problem.

Check the water inlet hose and the drain hose

Observe the safety precautions due to the risk of electric shock caused by water leakage. A dishwasher leak is normally contained by its anti-overflow safety system, or float. If water leaks under the machine, check the water inlet and outlet hoses. Follow the steps to check the external parts of the device.

Shut off the leaking dishwasher circuit for your safety

Safety above all. The risk of electric shock is increased when water leaks from a household appliance. If water invades the floor, shut off the dishwasher circuit from the electrical panel. Then, unplug the machine from the earth socket.

Check the seal of the water inlet hose

  1. Now that your safety is assured, shut off the water supply by turning off the tap.
  2. Loosen the water inlet hose and check the condition of the seal. If the seal is damaged, change it. Position the seal correctly and tighten the water inlet hose.
  3. Also check that the water inlet hose is not pierced or cracked. If there is a hole, change it to prevent water leakage. Check its reference on the spare parts list.

Check the water drain hose

The height of the connection of water discharge must be between 40 and 80 cm from the floor for emptying. If the draining is not carried out correctly, the water remains or rises in the tank causing a leak. Spread a mop on the ground and provide a bucket to collect the water.

  • If the machine is connected to the sink siphon, check if the siphon is clogged.
  • Check that the drain hose is not pushed too far into the water outlet of your installation. If the drain hose is pushed too far in, the siphoning cannot be done properly.
  • Check that the drain hose is not clogged. If so, uncork it with a mixture of boiling water, white vinegar, and baking soda. You can use a drain cleaner if you prefer.
  • Finally, check that the drain pipe and the water drain pipe are not perforated. Replace the defective part if necessary by taking its reference.

Check the inside of the dishwasher tub and its balance

If water is leaking from the door, check the inside of the dishwasher tub. Faulty door seals and spray arm, clogged filter, or rinse aid? Also, check the level of the machine feet. Follow the steps to check for parts that may be causing leaks.

Your foam machine?

Foam escapes from the dishwasher door during the wash cycle? Your device is not broken. This is either an overdose of rinse aid , or a faulty metering device. Always follow the dose of rinse aid indicated on the bottle to avoid leakage. The dispenser may be cracked causing an overdose of detergent . To check it, fill it with rinse aid. If after 48 hours the dispenser is empty, you can be sure that the part is leaking. Replace the proportioner according to its reference.

Check the gaskets and the closing of the door

  • If the water leak appears after washing, the door seals may be the cause. Check the door gasket to see if it is punctured or dirty. If the seal is damaged, replace it using its part number. Clean it if it is dirty.
  • Check that the door closes properly. Make sure that a poorly stored basket does not interfere with closing. Check the door for knocks. If the door is damaged, replace it.
  • If when you open the door you notice that it goes down to the floor, adjust the level of the feet. Place a spirit level on the device and make adjustments by tightening or loosening the feet.

Check the filter

The filter of your appliance should be cleaned after each wash. If it is full, it cannot be drained properly. Remove food residue from your dishes before placing them in the machine. If the filter is dirty, submerge it in hot water. Then clean it gently with a used toothbrush.

Contact plumbing and drainage experts

You have just checked all the external elements that may be causing the leak. If the device is still leaking, it might have serious problems. Do not disassemble the machine yourself. Firstly for your safety. Second, because the device warranty does not cover any damage you may cause. Contact the professional team as MidCity Plumbers for 24/7 plumbing and drainage services.

The failure may be due to a defect in one of the following spare parts:

  • the wash arms;
  • the solenoid valve;
  • the cycling pump;
  • the pressure switch;
  • the float.

Regular maintenance of your dishwasher and checking your installation will prevent any leakage problems. Regularly check the condition of the parts of your household appliance and its horizontal level.
