This article advises how I have replaced a Mira Shower thermal switch in a MIRA Sport 9kW Thermostatic Shower on several occasions.
Originally I installed a MIRA Sport 9kW Thermostatic Shower as part of a new bathroom and had it tested and certified by a qualified electrician on 1st May 2007. I was very pleased with it and it worked well for three years until June 2010 when it developed a fault.
I found that in the middle of taking a shower the water would go cold for a few seconds and then get warm again. On the first few occasions I wondered if cold water being drawn off by other taps and appliances was lowering the water pressure to the shower and so causing it to operate incorrectly (although the low pressure light was not illuminating). As the days went by the problem got worse and my wife ended up washing shampoo off with cold water. I knew then that I would be in bad books until it was fixed.
I had to determine if this fault could be fixed or if I would have to replace the entire shower unit. For this I needed to take a look inside the shower unit.
I could write an article about Building A Bathroom or Tiling A Bathroom but I have decided to just cover a Tiled Bath Panel in this article even though some detail of the tiles on the walls is mentioned. Bath panels can easily be made from painted hardboard or plywood, or boards, but a tiled panel can fit in with the rest of the bathroom very well when all the walls are tiled.
It must be nearly two years ago that I first had a problem with my Dishwasher Rinse Aid Dispenser Catch. The tab that has to be pushed towards the top of the door to open the rinse aid dispenser, so that more rinse aid can be added, had somehow broken and disappeared. I found I could continue to open it by pressing the remaining catch towards the top of the door using the handle end of a teaspoon.
Since refilling the rinse aid dispenser doesn’t happen everyday I was happy to continue with that opening method indefinitely. However about six months ago I found the entire catch was missing leaving the rinse aid dispenser door flapping in the breeze. I searched inside the dishwasher and found the plastic part of the catch but not the coil spring. Also when I inserted the catch its retaining clips no longer wanted to spring outwards and perform their retaining action. The whole plastic catch appeared to have been eroded by the dishwashing process. I noticed that the dishwasher liquid dispenser catch looks similarly eroded, but that works on a different principal and is still O.K. The detergent and rinse aid compartment covers are made of a different plastic which has not shown signs of erosion.
After several months without using rinse aid I decided I should take action to fix the catch.
