Luckily, this article offers five simple ways you can unfreeze your dishwasher. But before you discover how to fix it, here’s how to know your dishwasher is frozen.
You cannot fix a dishwasher problem if you don’t know its source. But you don’t have to be a dishwasher expert to notice the warning indicators of your dishwasher. Below are telltale signs that your appliance has run into problems.
The frustrations of dealing with a broken dishwasher
It’s easy to prevent your dishwasher from freezing by allowing it to run at night. In most cases, dishwashers get frozen at night when there’re low temperatures. You can use the control panel to program your dishwasher to run during the night.
Use the control lock to ensure no one resets or interferes with your programmed dishwasher. Make sure you leave the water faucet on to release water pressure and for all water to flow continuously through your pipes.
But after realizing your dishwasher is not draining due to frozen water damage, you may consider unfreezing it. Besides having frozen dishwasher problems, your dishwasher could have issues with the garbage disposal food debris. So, here are the easy steps you can use to fix it.
Here are some techniques to fix a dishwasher that won’t drain. If you’re not comfortable crawling around on the floor and under your sink - you may wish to just call the appliance repair person or plumber instead depending on your particular situation.
Hot water is perhaps the best remedy for dishwasher problems caused by freezing temperatures. With prolonged exposure to cold air, water in the pipes may freeze and cause a clog. It may even cause pipe damage (in which case it is time to call the plumber). If the issue is freezing with no visible damage, Hot water may solve this problem by thawing the ice within the drain pipe in an hour or so.
Here’s how to fix a clogged dishwasher using warm water:
Alternatively, blow some warm air under the dishwasher or the sink where the drain hose is. Attempt to get the temperature of the pipe back up to a typical room temperature. The process may take time, but with time the heat will hopefully unfreeze your dishwasher if it’s not a severe clog.
Frozen pipes are a major hazard - don’t apply excessive heat or else the pipe could burst
Never use extreme heat on the outside of any pipe that you believe is frozen. Doing so can have unintended consequences - like the pipe cracking or exploding.
The drain hose ensures water and food debris drains out of your dishwasher. However, your drain hose may become frozen if it’s freezing outside. Additionally, food debris may accumulate in the drain hose and cause a clog. In such cases, water will back up and rest on the tub.
The drain hose connects your dishwasher’s drain pump and the sink’s disposal. Before inspecting a clog, check whether your drain hose is kinked or damaged for replacement. Then, you can disconnect it from your dishwasher to check for blockage.
If the clog results from frozen water or food debris, you can blow air through it. What if blowing air doesn’t help? That could mean your hose is clogged at both ends. Use a wire to remove the clog.
If the clog doesn’t come out, you may need to replace the drain hose. Purchase a new drain hose from your local dealer and connect it to your drain pump and sink’s disposal. Fix it properly to prevent water from leaking or failing to drain out. Alternatively, call your plumber to fix it securely.
Your garbage disposal could be why your dishwasher won’t drain. If you suspect your dishwasher has a clog, it’s advisable to check the garbage disposal to unclog it.
When cleaning your dishes, dirty water drains through the garbage disposal. As the water drains, it leaves behind food particles and other debris. Continued use of your dishwasher means more debris is left in the disposal, and once it’s full, water won’t find space to empty into. As a result, water is left pooling in the tub.
You can fix this problem by running the garbage disposal to eliminate all food and debris. Open your tap to allow water to run down to clean the disposal and empty the remaining dirt down the drain. Run the disposal for 30 seconds while ensuring enough water supply to clean all the food and debris.
Drain cleaning can come in handy when unclogging any frozen water and food debris buildup. However, be cautious when drain cleaning your dishwasher.
Some commercial products used in drain cleaning contain toxic chemicals. After unclogging, chemical residues could remain in your dishwasher and might attach to your dishes during cleaning. The chemical may also damage your drain hose and other dishwasher parts.
Instead of using commercial drain cleaning products, you can use baking soda and white vinegar. The mixture will dissolve minor clogs and leave your dishwasher safe and running well.
To drain clean using vinegar and baking soda, pour the mixture into the drain hose and allow it to rest for 30 minutes. After the mixture has unclogged your drain hose, allow your dishwasher to run through a normal cycle to remove any residue. Make sure there’s enough water supply to run through the dishwasher.
Sometimes all you need to fix your dishwasher is by draining it manually. For example, if water is pooling in the tub, you can empty it using a cup. Alternatively, you can place a sponge or towel on the tub to collect the pooling water. When the level gets too low, use towels to absorb the remaining water.
Once you’ve scooped all the water, check the bottom to discover the cause of your dishwasher’s clog. If it’s the filter causing the problem, you can clean it or replace it. You can also inspect for food debris or a frozen dishwasher problem. After discovering the source of your dishwasher’s problem, fix it on your own or seek the assistance of a dishwasher repair expert.
