Temporarily DW motor failure due to Fairy tabs |

Last night I was really terrified...
I am not sure if this "Imperial" part of the site is the right place for writing this (apologies if not). I had a full load of dishes, put a Fairy Platinum tab in the detergent dispenser (first time using it) and ran the normal cycle in my Bosch. After prewash and about 15 minutes after the main wash started, there was a funy noise coming from the motor of the DW. Like the motor was struggling to perform... It was every 5-10 seconds and was lasting for 2-3 seconds. I thought that's it, the motor is slowly dying... I stopped it for a minute and start it again. When started, didn't do the noise, after minute, there it was again. I opened it and there were suds, not too much but I think enough for making the motor sucking air instead of water. So now I did an other cycle with out unloading the dishes, I just did not put detergent so I am sure that the suds caused the noise and there is not a motor failure... Did anyone had a similar experience? Could it was something else? If mine did like that, ( which is a 1995 model) Fairy tabs in a new DW that uses much less water than mine wouldn't aloud it to circulate any water..... What are your thought?? | ||

The DW was installed 15 days ago, it is old but never been installed before, I was the first using it so blockage in the water inlet ( aqua stop system) should not be the case.
Plus, we have super soft, rain water, we always have to use less detergent as they are not made for so soft water. My dishes were not heavily dirty at all, I bought new bowls and cookware and I wanted them to be washed but they were actually clean before... | ||

I agree with what washer111 said. It sounds like there wasn't enough water and the pump was sucking in some air. This could be because the tablets caused extra foam which prevented water from returning to the intake fast enough. If it happens again, add a liter more water to the machine and see if the problem goes away. If it does, you know it isn't a motor problem, but a lack of sufficient water.
My Bosch dishwasher will do that on occassion. Ever since I had the control board replaced (due to fire recall), it seems to cut off the water fill a bit earlier than with the old control board. So if water accumulates on the top of cups or other items, the amount of water circulating goes down and causes a little air to be pulled into the pump system. If I add 16oz of water, it solves the problem. I usually run the dishwasher when I go to bed, so I don't know if this happens very often. Even if I do hear it make that noise and do nothing, everything still comes out clean. | ||

Too sudsy ! 
Hello it's due to fairy tabs are way too sudsy for older machines which have higher water levels and higher pressure sprays. My mums 1990 aeg makes terrible rising and falling noises when using fairy. They are designed for average to hard water hardnesses, modern machines which use less water have lower pressures so cope ok.
Try old fashioned powder ie finish or sun or even Ecover ( Eco friendly tabs ) as they don't cause as much foam and give a nice pleasing wash sound. The noise doesn't actually harm the machine or result in poor cleaning but doesn't sound great. Good luck with your machine it will last you ages I hope ! Richard | ||

I used Finish Quantum tabs
And I noticed the struggling sound during the main wash too! It didn't kill the motor and I let it continue and everything came out great, but it made me paranoid to use them because you know that has to be harder on the motor. And I don't have soft water, so I could imagine how much foam they create with soft water.

somat powder does the same thing in my Miele Been using Somat (by Henkel) powder for a few years now and love it. If the dishes are not really dirty, it doesn't take much for it to generate some foam causing the motor to sound labored. Our water is pretty soft, auto softener on the machine is switched off, so that may add to it. The powder is great because you can dose to the size/soil level of the load. Tried the Somat 2 in 1 tabs and they were WAY too strong for us even with a full load of dirty dishes so the box just sits there. At least the box is pretty to look at. | ||
