How to Extend the Lifespan of Your Dishwasher and Solve Common Problems

A dishwasher is an essential kitchen appliance that saves time and effort. However, like any household device, it requires proper maintenance and timely repairs. Over the years, I have dealt with a wide range of dishwasher issues, from clogs to serious electrical failures. In this article, I will share how to extend your dishwasher's lifespan, the most common breakdowns, and when it's time to call a professional.

Most Common Dishwasher Problems

During my years of repairing dishwashers, I have most frequently encountered the following issues:
The dishwasher does not clean dishes properly
Food debris clogs the spray arm nozzles.
The detergent is low-quality or unsuitable.
The circulation pump that delivers water to the spray arms is faulty.
The dishwasher won't drain water
A clog in the drain filter or pump.
A kinked or blocked drain hose.
A broken drain pump.
Unusual noises during operation
Small objects (such as glass shards or food bones) stuck in the pump or circulation system.
Worn-out motor bearings.
A clogged filter, causing extra strain on the system.
These issues often result from improper use or the natural wear and tear of components.

Causes of Malfunctions and Solutions

Hard Water

Hard water leads to limescale buildup on internal components, reducing heating efficiency and cleaning performance. Solution:
Use dishwasher salt to soften the water.
Regularly run a cleaning cycle with vinegar or a descaling agent.
Clogs
A common cause of drainage and circulation problems is leftover food and grease buildup. Solution:
Clean the filter after each wash.
Check the spray arm nozzles and unclog them with a toothpick or thin wire if necessary.
Run an empty cleaning cycle with a dishwasher cleaner once a month.
Worn-Out Parts
Certain components, such as pumps, seals, and spray arms, wear out over time. Solution:
Look out for leaks or reduced washing performance.
If your dishwasher becomes noisier, the circulation pump bearings may be worn. In this case, it's best to call a professional.
⚠️ Important! Attempting to repair complex dishwasher components, especially electrical parts and pumps, can be dangerous. Dishwashers operate in a high-moisture environment, and working with electrical systems without experience can lead to electric shock. If you lack professional expertise, do not attempt repairs yourself-call a specialist!

How to Maintain Your Dishwasher Properly

Following simple maintenance rules can extend your dishwasher's lifespan and help you avoid costly repairs:
✅ Clean the drain filter every 1-2 weeks.
✅ Wipe the door seals to prevent grease and detergent buildup.
✅ Flush the spray arms at least once a month to prevent blockages.
✅ Use high-quality detergents suitable for your water type.
✅ Run an empty cleaning cycle every 1-2 months to remove grease and limescale.
✅ Avoid overloading the racks-proper dish placement improves cleaning performance and reduces strain on the pump.

When to Call a Professional

Some issues cannot be fixed without professional assistance. Call a technician if:
❌ The dishwasher won't turn on or displays an error code.
❌ Water isn't heating (this could indicate a problem with the heating element or temperature sensor).
❌ The dishwasher is making unusual noises, which may signal a circulation or pump issue.
❌ The machine is leaking-this could be due to worn-out seals or damaged hoses.
❌ You notice a burning smell-this may indicate overheating wiring or a faulty motor.
