Five Signs That Your Dishwasher May Be In Trouble

Posted on: 25 February 2015


Most dishwasher breakdowns can be avoided if you notice a problem in its early phases. The following common issues are usually reparable, but you have to act quickly if you want to save the appliance and potentially avoid a flood.

#1: Pooling Water

Water collecting in the bottom of the dishwasher after the cycle completes is one of the more commonly overlooked problems in a dishwasher, because many homeowners think this is normal. The fact is, your dishwasher should drain completely by the end of the cycle. Pooling water is usually indicative of a clogged drain or drain line. Scheduling a drain repair and cleaning prevents a future flood. It also ensures your dishes are properly cleaned and that mold doesn't begin growing inside the dishwasher.

#2: Drop In Water Temperature

The water in the dishwasher must reach between 120 and 150 degrees Fahrenheit to properly clean and sanitize your dishes. If you can open your dishwasher immediately after the cycle ends and the dishes don't feel hot or there is no steam present, hot water isn't getting into your unit.

Most dishwashers draw from the hot water heater. If the water from sink taps is still hot, then your dishwasher isn't drawing from the hot water lines and it will need a repair. If your tap water won't heat up, then the issue is with the hot water heater. Some dishwashers heat their own water, so these may need the heating element replaced if the water is running cold.

#3: Residue on the Dishes or Dishwasher Interior

Dirt and residue on dishes and the inside of the dishwasher can indicate one of several problems. Often, the issue is as simple as debris buildup in the trap at the bottom of the unit. Simply locate the drainage trap and clean out the buildup.

Residue can also indicate clogged sprayer arms. Hard water is often the culprit. If a hard water treatment and trap cleaning doesn't solve the problem, schedule a prompt repair so you can avoid a costly replacement.

#4: Loud or New Noises

Some dishwashers are louder than others, but if yours suddenly begins running louder, shaking, or squealing, it's time for prompt service. The problem is likely with the motor, which may require a repair or replacement. Putting it off can cause irreparable damage to the appliance, or even damage your dishes.

#5: Poor Input Response

Many modern dishwashers use touch pads instead of buttons for setting the cycles. These should respond immediately to your input. If touch pads become unresponsive, they will need servicing or replacement. Another issue is if the door lock begins to fail. If the door doesn't latch properly, the dishwasher can pop open in the middle of a cycle, resulting in a big mess.

Although you can complete minor repairs yourself, major repairs are best done by professional appliance repair in Surrey. They can advise you on when it's more cost effective to replace, rather than repair.
