This problem is quite common, especially among units that have been used for a long time, intensively, without following the rules of operation. If you need Bosch dishwasher repair in Cambridge, you can ask for help from repair specialists.

Possible Causes Of Failure
The reasons for the lack of heating are the same regardless of the brand. Conventionally they can be divided into three groups:
Bosch dishwasher does not heat water
1. Wrong Connection
If the new dishwasher does not heat the water, it may not be connected correctly. This usually occurs with the so-called “siphon effect”, when the water is constantly drawn in, drained out and, therefore, simply does not have time to heat.
Such a situation is possible when installing old equipment in a new place (moving to a new apartment, buying a used dishwasher) or when using old hoses.
2. Errors in Operation
The most common cause of a dishwasher that stops heating water is a clogged filter. It should be cleaned after each wash cycle, not occasionally. A clogged filter reduces water circulation. With poor circulation, the heating element does not turn on, and the water remains cold.
There are also trivial errors in selecting the program (instead of an intensive cycle, low-temperature mode or delicate washing, for example). Sometimes such a program failure occurs “thanks” to small children or pets. In electronic-mechanical models, the appliances “by default” work in “electronic” mode and heat water to the temperature set in the program.
3. Technical Breakdowns
The main “culprits” due to which the dishwasher stops heating water are:
Heating Element;
temperature sensor (thermostat);
Control Module.
When these elements malfunction, it is impossible to do without professional repair. In addition, the cause of malfunctioning of the water heater can be a pressure sensor, burned contacts, etc. Attempts to find out the causes and fix the problems yourself can lead to more damage to the equipment. Therefore, if repair is required, contact the professionals.
Ways to Fix the Breakdown
First, check if everything is in order with the software settings, and turn on the desired temperature mode.
Ensure the machine is connected correctly and the water is not constantly draining. Theoretically, you can “reconnect” the equipment on your own, but it is preferable to entrust this procedure to a master who will install according to the requirements.
The third step is to check the filter. The clogged filter must be cleaned. But if all these measures do not bring the desired result, and the water still does not heat, call a professional. The master will diagnose and determine what needs to be replaced or repaired and then perform dishwasher repair.
If the heating element is burned out, it must be replaced. Heating elements, unfortunately, are not repairable. But the good news is that such problems are repaired quickly – in an hour maximum, the equipment will work again.
In case of failure, the thermostat (temperature sensor) is also subject to replacement. The cost of installing this part is relatively low, and you can repair the dishwasher without delay.
Two options are possible when the water does not heat due to faults in the control module: “reflashing” or replacing the element. What exactly is required? The specialist will be able to say only after completing the diagnostics.
At the first sign of malfunction, call a specialist – fixing minor problems will be much cheaper than replacing expensive parts that have malfunctioned as a result of using a faulty dishwasher.
