Reasons for Blinking Dishwasher Lights

There’s nothing more annoying than starting the dishwasher at the end of the day and being confronted with blinking lights. Suddenly, you’re elbow-deep in soap suds after emptying the dishwasher and worried about the cost of repair.

What to Do First

There are many reasons why your dishwasher could be dead. Fortunately, most of the problems can be fixed for a reasonable cost, saving you the hassle and expense of purchasing a new dishwasher.
If you’ve kept your dishwasher manual, it’s time to dig the booklet out. It’s possible you may be able to fix the problem yourself by following the advice of the manufacturer. Some dishwashers have a display window. If yours does, check the fault code in the manual to see what’s going on. This can make the repair easier and faster if you need to call in the experts.

Possible Causes of Blinking Dishwasher Lights

A common reason for blinking dishwasher lights is a heating element that has stopped working. The heating element ensures that the dishwasher’s water is heated to the right temperature at the right time. If the water isn’t hot enough, the lights may blink. A quick solution may be as simple as running the hot water in the faucet by the dishwasher. This will help heat the water coming from the house so it’s easier for the dishwasher to heat. If it’s an ongoing problem, you may want to call in an appliance repair expert to take a look.
Water pressure may be another issue causing blinking lights. It’s simple to test the water pressure. Just place a cup upright in the top rack instead of placing it upside down. Set your dishwasher on the normal cycle and run it for ten minutes. Stop the dishwasher and check the glass. If it has filled with water, the water pressure in the dishwasher should be fine. If the cup hasn’t filled much, then the blinking lights are likely warning you that there is a water pressure problem in the dishwasher.


The drain pump is another part that can cause the dishwasher lights to blink when it stops working properly. The drain pump pushes water through the drain hose so the dishwasher drains properly. When it stops working, you may find a small lake at the bottom of your dishwasher at the end of a cycle or even experience overflow as used water doesn’t drain. Unfortunately, a broken drain pump can’t be repaired. If this part is causing the dishwasher lights to flash, it will need to be totally replaced.


The blinking lights may also be related to the touchpad or the control panel. This problem will need expert attention. A tip off that the touchpad has stopped working properly is that some of the buttons don’t work with only one touch or don’t work at all. Instead of learning to live without the eco cycle or heavy cycle, it’s time to call in an expert and fix the problem.


There are many reasons why the lights on your dishwasher may be blinking so if you’re uncertain, call an experienced appliance repair company to assess the problem.
