Dishwasher Not Getting Hot

When it comes to running smoothly, nothing is more frustrating than having a dishwasher that does not get hot. A lack of hot water can lead to dishes that are not properly cleaned and sanitized, leading to an unhealthy kitchen environment. Unfortunately, this type of problem is all too common with dishwashers. Today, we’ll discuss some of the most common causes for a dishwasher that isn’t getting hot and what you can do to solve the issue.

Common Causes of Dishwasher Not Getting Hot:

The dishwasher is a staple item in many homes and businesses around the world. It’s an important piece of equipment that helps to keep dishes clean and sanitary. Unfortunately, issues with a dishwasher not getting hot can be quite common.

In order to identify and fix the issue, it’s important to understand what may cause it in the first place. Some of the most common causes of a dishwasher not getting hot include faulty heating elements, broken thermostats, or clogged filter screens. Issues with the power supply can also result in insufficient heat for proper washing cycles. A blocked water hose may also prevent hot water from reaching your dishwasher as well.

In some cases, you may need professional help to diagnose and resolve these problems safely and quickly.

Fixing the Heating Element:

A broken heating element in a dishwasher can be a frustrating problem. If you’re having trouble with your dishwasher not getting hot, it could be due to a faulty heating element. Fortunately, this is an issue that can be fairly easily fixed at home without the need for professional help.

To determine if your dishwasher’s heating element is indeed malfunctioning, start by checking the thermostat and temperature switch. You may need to use an ohmmeter or voltage tester to accurately diagnose these components. If either of these parts are determined to be faulty or damaged, they should immediately be replaced as they are responsible for controlling the flow of electricity from the power source to the heating elements in the dishwasher.

Once you’ve identified and replaced any broken parts, test out your dishwasher again and see if it gets hot when running.

Fixing Thermostat:

It is common knowledge that a dishwasher needs hot water to properly clean dishes, but what do you do when your dishwasher isn’t getting hot? The first step in troubleshooting a dishwasher not getting hot is to check the thermostat. The thermostat maintains the temperature of the water in the dishwasher and can sometimes become misaligned or malfunction, resulting in lukewarm or cold water. Fortunately, fixing a broken thermostat is a relatively easy task.

To begin with, you will need to locate and remove the access panel on your dishwasher. After removing it, locate the wire connected to the heating element and pull it off; this will make it easier for you to check for continuity using an ohmmeter. If there is no continuity present, then you know that your thermostat has gone bad and needs to be replaced.

Checking for Blockages:

Over time, food particles and other debris can accumulate and cause blockages, leading to water not being heated up correctly. Fortunately, there are some simple steps you can take to ensure your dishwasher is free from blockages.

First of all, check the dishes for any large chunks of food or other debris which may be blocking the water jets. If you find anything that could be causing an obstruction, remove it carefully using a pair of kitchen tongs or similar tool.

You should also check the filters for signs of build-up as this could be preventing the water from heating up properly. Clean out any debris found here with an old toothbrush or soft cloth and then run a cycle with no dishes inside to make sure everything is clear.

Cleaning Out the Filter:

Are you having trouble with your dishwasher not getting hot? The problem may be due to a dirty filter. Cleaning out the filter is an easy task that can be done in just minutes and should be done regularly.

 The filter of a dishwasher traps food particles and other debris, preventing them from recirculating through the system. Over time, the filter will become clogged with dirt and grime and needs to be cleaned regularly to ensure it is functioning properly. This will help keep your dishes clean and ensure that your dishwasher gets hot when in use.

To clean out the filter, first locate it at the bottom of the dishwasher. It’s usually underneath a large plastic cover plate or at one end of the tub.

Checking the Temperature Valve:

it’s time to check the temperature valve. This rarely-considered part of the machine can cause a variety of symptoms and needs to be checked if other parts of the dishwasher aren’t responding correctly. A malfunctioning temperature valve can lead to dishes that remain cold and soapy despite running a full cycle.

The first step in troubleshooting is locating the temperature valve. Depending on your model, it may be at the back or bottom of the dishwasher interior, often behind a removable panel, or near where the water line connects.

Once located, ensure that there is no visible damage such as corrosion or clogging from mineral deposits from hard water buildup. If everything looks normal but still isn’t working properly, you should replace this part for optimal performance

Resetting the Dishwasher:

It may be time to reset your dishwasher. This solution is rarely necessary but can help restore normal operation in some cases. Resetting the dishwasher is a relatively simple process and can save you from needing a costly repair or replacement of the machine.

When you’re ready to reset your dishwasher, start by unplugging it from its power source for several minutes before plugging it back in. Doing so will give the appliance enough time to allow all electronics inside to cool down and reset themselves. After that, run your dishwasher’s cleaning cycle on a high temperature setting without any dishes inside – this will further help clear out any clogs or blockages within the system.

Preventative Maintenance:

With today’s busy lifestyles, it is more important than ever to make sure that the appliances in your home are running efficiently. Preventative maintenance is key to keeping your dishwasher up and running for years and avoiding costly repairs.

One of the most common issues with a dishwasher not getting hot is a clogged filter or an issue with the heating element. If you notice that your dishes aren’t coming out as clean as usual, or water isn’t draining from the appliance, then it may be time to check your filter.

Make sure to clean it regularly to ensure that food scraps don’t accumulate and block water flow. It can also help if you scrape off any large food particles before loading dishes into the washer. Doing this will help keep things running smoothly and reduce the strain on other parts of your dishwasher.

Repair vs Replace:

When it comes to a dishwasher not getting hot, one of the most important questions faced by homeowners is whether to repair or replace their appliance. Repairing an old dishwasher can be cost-effective and efficient, however there are some key factors that must be taken into consideration before deciding which option is best for you.

The age of the dishwasher should play a major role in your decision making process. If your appliance has seen better days, then replacing it may be a more economical choice than repairing it. Additionally, if repairs would only extend the life of your current model by a few months or years, then replacement might also be wise as it could potentially save money in the long run due to higher energy efficiency and other features found on newer models.


Troubleshooting a dishwasher when it’s not getting hot is a tricky process. It can be time-consuming and require specialized skills and tools. With some patience, however, and a thorough examination of the appliance, most people can diagnose the problem and perform the necessary repairs. If you’re uncomfortable or uncertain about any step in the process, consider hiring an experienced professional to help. By following these tips, you should be able to restore your dishwasher to proper working condition quickly and easily.
