A blocked dishwasher usually starts off as something minor but it doesn’t take long before it becomes a proper inconvenience. You might notice water sitting in the bottom after a cycle, it draining slower than usual, or even a bit of a smell starting to build up. Most of the time it’s not just the dishwasher itself, it’s something going on in the waste line or pipework connected to it.

Dishwashers need a clear path for the water to drain out every time they run. When that line starts to block up, whether it’s from food scraps, grease or general build up over time, the water can’t move through like it should. That’s when you start seeing it sit in the base or back up into the unit. Sometimes it’s right at the hose connection, other times it’s further down the line near the sink or main drain, so it’s important to look at the whole setup rather than just the appliance.
We see a fair few where it’s not only a blockage. Sometimes it comes down to how the dishwasher has been set up in the first place. Little things like the way the hose runs or how it’s connected can cause problems that keep coming back. It’s not always obvious straight away, but once it’s picked up and corrected, the difference is noticeable pretty quickly.
When we attend, we go through everything step by step to work out exactly where the problem is coming from. In some situations it’s a quick clear, in others it might need a bit more work to get it draining properly again. Either way, the focus is on fixing it properly so you’re not dealing with the same issue again in a few weeks.
If your dishwasher isn’t draining properly, it’s always better to deal with it sooner rather than later. Leaving it can lead to water damage inside the cabinetry, ongoing smells and more build up in the pipework. Once it’s cleared and flowing the way it should, everything runs a lot smoother again.

Frequently Asked Questions
