Common Dishwasher Plumbing Problems

The dishwasher is one of the most-used appliances in the home, especially during the summer months when you’re having BBQs all the time, you’re entertaining guests and you’re too busy having fun to be washing the dishes. But increased use also means a higher chance of something breaking or becoming damaged, and there are a number of common dishwasher plumbing problems that we often experience especially as the appliance gets older. Here are a few common issues to look out for and what to do if you experience a broken dishwasher.

Dishwasher not draining

One of the most common dishwasher plumbing problems is that the unit isn’t draining properly. Often, if the sink isn’t draining then the appliance won’t either as the two are connected. So if you’re dealing with a sink clog you should call out Mr. Plumber to fix the blockage, and that should solve both clogs. It could also be caused by a blockage in your garbage disposal or a non-functioning garbage disposal unit.


Another common issue with dishwashers is leaks, and this can actually be very damaging to the structure of the home if you don’t get it looked at. Such leaks are often caused by the pump which may have deteriorated over time. Or it could be caused by a problem with the seal around the door. Or it may be caused by a problem with the water inlet valve that feeds water from the pipe into the dishwasher. It could also be that one of the hoses is leaking or has a small crack that is causing water to escape. A common indicator of a leak is pools of water underneath, staining on the floor, and musty smells coming from underneath the appliance.

Clogged filters and pipes

It’s so important to rinse your plates and use products to cleanse your dishwasher, but sometimes dirt and sediment can accumulate and cause clogs in the filters and pipes. Initially, try to remove any visible food scraps that you can see around the bottom of the unit, but if that doesn’t work it may be time to call out your plumber to take a proper look.

If you suspect any plumbing issues with your dishwasher, don’t leave the issue to get worse before you get it looked at as you can cause serious damage to your unit and home in the long run. Get in touch with Mr. Plumber Vancouver today if you’re looking for a plumber in Vancouver to help fix the problem.
