Don't Ignore These Dishwasher Warning Signs

Whether you run a restaurant, cafe, or hotel with catering amenities, a dishwasher is your trusty kitchen companion that quietly takes care of the dirty work day in and day out. But what happens when it starts sending distress signals you can't afford to ignore?


Here are the key indicators that it's time to take action. Addressing minor issues timely, you can avoid major issues and save a lot on commercial dishwasher repair.

1. Unpleasant Odours

One unmistakable sign that your dishwasher needs attention is a foul odor emanating from it. If your once-freshly cleaned dishes now smell worse than they did before washing, it's time to investigate. Often, this indicates a buildup of food particles and grease in the filters or spray arms.

2. Inefficient Cleaning

If your dishes come out with remnants of meal still clinging to them, your dishwasher isn't doing its job. It could be due to clogged spray arms, a malfunctioning pump, or even hard water buildup. Regular cleaning and maintenance can resolve these issues.

3. Loud and Unusual Noises

Dishwashers are supposed to operate quietly. If yours has suddenly started making clunking, grinding, or rattling sounds, it's time to investigate. These noises can signal anything from a loose spray arm to a malfunctioning motor.

4. Leaks and Puddles

A pool of water under your dishwasher is a serious issue.It may suggest a drainage issue that could lead to water damage or mold growth. Check for debris in the drain filter. Also, check for loose hoses, damaged gaskets, or a faulty door seal. If the problem persists, it might be time to call a professional.

5. Long Cycle Times

Dishwashers have a set cycle duration. If you notice the unit taking significantly longer to complete a cycle, it might indicate a problem with the heating element or the control board. Extended cycles also increase your energy bills.

6. Soap Residue

Soap residue on dishes or inside the dishwasher suggests that the detergent isn't dissolving properly. Check the detergent quantity and quality. Using too much detergent can create excess suds, which interfere with proper cleaning.


Your dishwasher is a vital part of your kitchen, and ignoring warning signs can lead to inconvenience and costly repairs. By staying vigilant and addressing issues promptly, you can keep your dishwasher running smoothly, the dishes sparkling clean, and the customers happy and loyal.
