Bosch dishwashers offer buyers various models that can fit just about any need, spanning from basic designs for those who only need a great clean to those models that offer a third rack that gives one of the highest place settings among other brands.

Bosch Dishwasher Heating Problem

Although there are various settings on a Bosch dishwasher that are designed for delicate items, heavily stacked loads, or loads that need a quick rinse, during the cycle, heat must be used in order to sanitize and dry the dishes once the washing cycle has completed. If you have a Bosch dishwasher that is not heating as it should throughout the cycle, continue reading below to see what can be done to get this aspect of your appliance back to working order.

Bosch dishwasher heating problems can be resolved by checking to make sure that the automatic shut off feature has not been enabled, confirming that the water has been turned to a high enough heat, and running the hot water at the sink connected to the dishwasher for 30 seconds before starting a cycle.

Bosch Dishwasher Won’t Heat Up

During the sanitization portion and drying portion of the cycle, Bosh dishwashers use hot water and steam to ensure that the dishes have been thoroughly cleaned and dried before they are removed from the appliance. If you pull the dishes from the dishwasher soon after the cycle has completed, you may notice that the dishes are hot and perfectly clean. However, if you notice that the dishes are cool and still have residue on them, it could be that it is not heating up.

If your Bosch dishwasher won’t heat up, check to make sure that the automatic shut off feature has not been accidentally turned on. If this has been activated, the dishwasher may shut off mid cycle, which will prevent it from ever reaching the stage of sanitizing with hot water.

Bosch Dishwasher Not Heat Drying

There are few things more frustrating than pulling out a full load of dishes and seeing that each is completely soaked and saturated with water. At the end of a wash cycle, no matter what cycle you choose, there should be a drying stage that works to repel the water as quickly as possible before the cycle completes. If you notice that your Bosch dishwasher is not heat drying and your dishes are wet when the cycle competes, what can be done?

If your Bosch dishwasher is not heat drying, this is because Bosch dishwashers don’t use a heating element to dry dishes, but use a condensation method that produces one last hot rinse. When paired with the stainless steel interior, this promotes the water to drip off at a faster rate.

Bosch Dishwasher Not Hot Enough (to Dry)

As previously noted, a Bosch dishwasher doesn’t use a standard heating element to dry the dishes, but completes one last hot water rinse that works with the stainless steel interior to condensate the water and force it to drip from the surface of the items. However, the water during this last rinse needs to be at a high enough temperature to create that interior condensation. If the dishwasher isn’t hot enough to dry, what might be the problem?

If your Bosch dishwasher isn’t hot enough to dry, be sure that your water heater has been turned up to a high enough temperature. Once heated, turn on the sink and allow the hot water to cool for 30 seconds. When this time has passed, complete a cycle and see if the dishwasher heats.

Bosch Dishwasher Overheating

Opposite of the previous problem of a Bosh dishwasher not heating enough to dry the dishes is the issue of a dishwasher overheating. When this happens, you may physically be able to feel the heat dispelling from the appliance, or you may smell something like burning plastic. Either way, the overheating of a Bosch dishwasher does not only pose a threat to the appliance, but also to the safety of the area and the people the appliance is located.

In multiple portions of the washing and drying stage, a Bosch dishwasher has to use the powers of hot water to sanitize and start the drying process for the dishes within. If the water is not heated, the dishes will be left with food residue as well as dishwashing liquid covering them. If you notice that the water is not heating within your Bosch dishwasher, read on to see what could be the problem and what can be done to fix it.

Bosch Dishwasher Water Too Hot

Owners of Bosch dishwashers may not think anything of it if they know that the water is heating properly and thus, cleaning their dishes how they should be. However, if you start to notice that plastic pieces are coming out warped or that glass items are coming out cracked or chipped, this could be an indication that the water is too hot. If the water in your Bosch dishwasher is too hot, how can the temperature be decreased?

If the water in your Bosch dishwasher is too hot, the most likely issue is that the water temperature within your water heater is set too high. If the water heater is at a temperature that is nearly boiling, be sure to decrease the temperature, allow time for the change to take place, then run the wash.
