So, grab the operating manual if you have it, find a towel to clean up the leak and get something clean up any further leaks and see if you can’t fix the problem. If you can’t call us for local dishwasher repair.
A lot of the more common causes of dishwasher leaks are not actually due to a broken dishwasher at all. Prior to starting getting the tools out and flicking through numerous YouTube tutorials there are a number of problems you can troubleshoot first.
If you have ruled out these possible causes it’s time to get ready and start a thorough check.
To make your life easier start with the door as well as test for any visible problems within of the machine prior to moving on to the underneath. If you can find and so resolve the problem without pulling out the dishwasher you’ll save yourself a lot of hassle.
And make sure you disconnect the appliance first by either unplugging it or turning off the circuit breaker for the dishwasher.
The most common place for a dishwasher to leak is on the door, thankfully it is also one of the quickest issues to resolve.
If the leakage is periodic the problem could be as simple as a large plate or something else pushing against the door thus stopping it from closing fully.
On the other hand the door gasket could have been dislodged or become cracked.
Examine the door seal and test for any degradation, a build-up of limescale or other debris, or any areas in which the seal might have come away from the door.
Taking off the seal and giving it a good clean has been known to improve the situation in some cases or you may be required to buy a new gasket and replace it.
The water inlet valve can also be a commonly seen issue. The inlet is in most cases located underneath the machine therefore you will need to take off the toe board and could have to remove the door cover.
The inlet valve opens and also closes to let water into the tub at various parts of the program. The fill valve may be leaking, evidenced by a slight drip, or it may be broken and not operating correctly during the program.
If the fill valve doesn’t shut properly this can mean that the dishwasher overfills, causing a leak.
Usually these valves can’t be repaired, and so the entire valve would need to be changed.
Hoses are needed to fill, empty and also recirculate water within the cycle.
Two complications could develop where hoses are concerned.
Luckily broken hoses are easy to buy as well as change.
You can visually check the rubber seals that are part of the water pumps or motor to see whether there is a leak and change them if that’s the case.
The float itself or the float switch could be not working correctly causing the dishwasher to overfill.
When working as it should the float will go up as the water rises until the desired or maximum water level is attained. The tag of the float will then operate the switch. A blockage or breakage could be your issues.
Testing the switch would need a multi-meter although it could be obviously damaged in which case getting a new one should stop the leak.
A broken wash arm or support could causing a leak. This could also often affect how well your dishes are being cleaned.
Broken or faulty lines could also cause this problem as might a loose pump cover.
The motor shaft seal might have cracked resulting in leakage. This generally presents as a puddle coming from the underside of the machine.
If the root of the leak is still a mystery the thing you could do is to pull the dishwasher away from the wall to get better access underneath it and also add water to the tub to see whether the leakage presents itself.
If this doesn’t shed any light your machine may only leak if the pump is running. In this instance, you should employ a qualified technician to diagnose as well as resolve the fault due to the safety risks of checking for faults with electrical elements exposed.
