A leaking portable dishwasher could create serious problems if you don’t address it quickly. If it is leaking where you can see it, it is likely there’s also water where you cannot see it. If that’s the case, then you may have a larger problem than simply a wet floor.
Should there be moisture and warmth left for any amount of time, mold and mildew will quickly follow. Untreated mildew and mold in your home could potentially cause serious health issues, particularly if you have a baby. Because of this, you need to quickly find and repair any leak, as well as clean and treat any residual water left behind.
Step 1 – Inspect the Door Seal
As with many appliances, the front door of a portable dishwasher has a rubber seal around the inside edges which keeps the water and soap trapped inside the unit. If you discover dry rotted or torn seals, then this is probably the source of the leak. You should visually inspect for nicks or cuts. If you don’t see anything, use a small piece of newspaper or note paper and set it between gaps along the top of the door. After closing the door, gently try and pull out the piece of paper. If the piece of paper does not come out of the door, open the door and move it over slightly. Close the door and try again, going all the way down the seal. If the gasket for the dishwasher door is good, pulling the paper out should not be easy.
Step 2 – Inspect the Water Supply and Return Lines
Another cause of your leak could be the two hoses attached to it. Before starting any work on an appliance, unplug it first. After you remove electrical power, turn the dishwasher around and inspect the water supply line located near the bottom of the unit.
Previously I mentioned the two lines that attach to the washer: the inlet and outlet hoses. They are approximately one and a half inches in diameter. Once you have your dishwasher situated, feel along the length of them and see if you feel wetness. If it is wet at the hoses, look for punctures in the lines. Any damage will call for a replacement. Lastly, check all the hose attachment points and the faucet connection for leaks. If the supply or return lines are leaking at the connections, tighten them.
Step 3 – Check to Ensure no Leaks at Pump or Inlet Valve
The inlet valve has a flap that opens up and allows water to be introduced into the washer tub, and the pump disperses and drains the water. The valve rests on top of the water inlet line near the bottom of the washer. If you find the line at the pump corroded, this could be where the leak is originating. There’s a seal in the pump you want to check also. Remove the pump to inspect, but also check the pump housing to see if it is cracked. If so, replace the entire pump assembly.
Step 4 – Check the Water Level
If inside cabin of a portable dishwasher gets too full, that can cause your dishwasher to leak. You’ll want to run your washer (without dishes) until it stops in the cycle. When you hear the water cut off, open the door and check inside the cabin. The water should not be any higher than the lower edge of the dishwasher door. If it is, make sure there is nothing clogging the drain port.
Another thing you might want to check is the plastic float in the bottom of the washer. If it is damaged or not operating correctly, it will not signal the inlet valve to close. Lastly, and this should be first, check to make sure you are not overloading the dishwasher. Consult your owner’s manual for the proper loading procedures for your washer. The malfunctions discussed in this article are certainly not the only ones that can cause your washer to leak, but they are typically the most common ones. If your washer still leaks after trying these inspection tips, you might want to call the customer hotline or a plumber.
