Identifying Low Dishwasher Temperature

If your dishwasher is not adequately washing your dishes, the system's water temperature might be the source of your issue. The same way you take a hot shower to clean your skin, your dishwasher uses hot water to clean your dishes. If the water is not hot enough, your dishwasher will not perform up to par.

Why Aren't My Dishes Clean?

Your dishwasher has one job: to wash your dishes. Yet, it can only do so if the water inside the system is adequately hot. Hot water helps to properly clean your dishes and the dishwasher itself, as well as to fight off germs and bacteria. If your dishes are coming out dirty, it may be because the water temperature is too low.

How to check for low water temperature

  • During the wash cycle, the dishwasher should get hot enough to create steam. Open the door slightly while the dishwasher is still mid-cycle. You should see steam escape from the gap. If you don't see any steam, your dishwasher isn't getting hot enough to clean your dishes properly.

    CAUTION: Stand back a bit and open the door carefully. Water shouldn't splash out, but it's best to be cautious.

  • Once the cycle ends, feel the dishes inside and determine whether they are hot to the touch. If they're only warm or even cold to the touch, your dishwasher isn't getting as hot as it should be to clean the dishes properly.

If the temperature seems fine, consider other reasons for dirty dishes.

What To Do If Your Dishwasher Water Temperature is Low

If your dishwasher water temperature is, indeed, too low, you may need to adjust its settings. How to do so will vary by model, so consult your dishwasher system manual to adjust the water temperature.

Didn't work? If the water is still too cold, you're probably dealing with a faulty heating element or something more complicated that requires an expert's discretion. You can reach out to our Remote Assist expert for a virtual diagnosis!
