My old Bosch dishwasher can run at a temperaure of 55 C or 65 C. My dishes are not very dirty and I tend to use only 55 C. Is it good practice to occassionally run at 65 C to help keep the machine clean or is it better to use some dishwisher cleaner instead?
I know that occassionally running a laundry washing machine at a high temperature helps keep it clean and wonder if the same applies to a dishwasher.
if you want to use a 55 or 65 degree programme that should be fine short term to long term.
Dishwasher cleaners ( whilst using either temperatures as above) on a Bosch will only make the areas you see look clean but would have a minimal effect on the grease / general deposit build up within some internal pipe work and the fill matrix.
Your answer to the washing machine powder left overs to mix within your new box of powder should not be a problem, so yes you can, same goes for the liquid to liquid. I`ve never had a problem so I cannot see why you should get problems either.
