Common Reasons Why Your Dishwasher Might Be Leaking from the Bottom

Understanding what’s causing your dishwasher leak helps you stop the problem at the source. Here are the most common culprits:

– Worn door gasket – Cracks allow water to escape easily during a wash.

– Faulty water inlet valve – If the valve isn’t closing properly, excess water can pool underneath.

– Broken water pump system – A leaking or damaged pump can cause water to flow where it shouldn’t.

– Clogged filter – Food bits and debris can block the filter and lead to leaks.

– Loose or damaged hose clamps – If compromised, they’ll start dripping underneath.

How to Check for Leaks in Your Dishwasher

If you’re based in Reservoir, Moonee Ponds, or anywhere across Melbourne, a simple check could help you avoid costly damage.

1. Inspect the door gasket – Look for cracks or flattened spots.

2. Examine the drain hose – Check for bends, cracks, or loose connections.

3. Check the water pump – Ensure it’s securely mounted and not leaking.

4. Look under the unit – Remove the kickplate and inspect for pooling water.

5. Test the float switch – This part prevents overfilling. If stuck, it can cause overflow.

Hidden Causes Behind a Dishwasher Leak

Sometimes, a leak isn’t obvious. Underlying issues can lurk in places you might overlook:

– Water inlet valve damage – A slow leak from this part can build over time.

– Spray arm issues – Cracks or clogs can cause water to spray off course.

– Heating element corrosion – Rust or damage can weaken the basin and lead to leaks.

Regular inspections make a difference. That’s why 247 Plumbelec offers fast, honest help throughout Melbourne, from Strathmore to Fitzroy North.
