How the heat exchanger works
Located at the back wall of the left chamber, the heat exchanger works to regulate the temperature of the water. Dishwashing involves using water in almost every stage. Water mostly comes from the source as cold water, and so the heat exchanger will regulate that water so that the resulting water will be of suitable temperature even to wash off oily dishes.
Basically, cold water flows in during the dishwashing process then the heat exchanges with the hot water. The result is that the cold water also heats up. When the water gets heated to optimum temperatures, it enters the dishes at every stage of the washing process.
The efficiency of heat exchanger technology in the Siemens dishwasher cannot be overlooked. Energy consumption, which is a significant consideration for everyone using any kind of electronic, is low with this device. Besides, the technology ensures that thermal shock is wholly excluded, thus guaranteeing safety to the individuals using this device.
How to fix error code E19
Fixing of error E19 primarily entails replacing the heat exchanger’s drain valve.
- Start by disconnecting the Siemens dishwasher from the primary power source. This is mainly because you are dealing with a sensitive where electric currents go through.
- Drain water from the device such that not even a little amount is left. Use a convenient manner to drain water. It’s recommended that you follow the manufacturer’s instructions when doing so.
- Locate the drain valve and turn it in a clockwise direction
- When you get to the turning limit, pull the valve from the heat exchanger.
- Get a new valve and fix it. You will use a reverse rotation approach; that is, you’ll rotate it in an anti-clockwise direction until you get to the limit.
- Plug your appliance back to its main and begin the dishwashing process.
It is important to keep in mind that if you suspect problems with the heat exchanger and you want to dismantle it as a whole, it’s not necessary first to remove the drain valve. You can disassemble it wholly and fix a new it as a whole again.
