ONE YEAR AFTER moving into a new house, our Bosch Classixx washing machine stopped running normal wash cycles. It would stop before rinsing and even when the rinse mode was manually selected, it would not rinse. This started happening at the worst time--in the winter. I have never seen a Bosch appliance roll over and die after a year so I wonder if something else was causing the washing machine to stop working. A little investigation suggested that new floor tiles in the house (see left) was contributing to the problem.
We have just tiled over top an underfloor heating system. Now the house gets to a warmer temperature faster than it did with a bare concrete floor. Once the floor is up to its correct temperature, the excess heat circulates into our hot water immersion system.
I looked at the back of the washing machine and discovered only the hot water lead was connected to the washing machine. The water supply to the washing machine comes from the immersion. In the winter, when the house is heated, the immersion gets residual heat from the underfloor system. That water is too hot for the rinse cycle of the Bosch washing machine so the machine will not accept the water and it will not rinse when asked.
After I disconnected the hot water and connected cold water to the back of the washing machine, everything worked just fine.
The tiling job is part of the "Mellifont" photostream.
