I wonder why in this day and age manufacturers are still using noisy pumps on their washing machines (especially noisy/growl'y at the end when there is no more water to pump out) - I have a 10 year old Dishwasher that pumps out the water into the drain lovely and quiet and smoothly.
I understand that dishwashers have a different type of pump (a recirculating pump) but why could they not fit the same kind of pump to washing machines too? or even at least on high end / mid range washing machines at least (have the likes of Miele etc got quieter pumps?) - would there really be a huge difference in manufacturing costs of fitting a dishwasher type pump to a washing machine?
You are in a scenario of having a nice quiet brushless induction motor .. and then you have this noisy growly vibrating pump noise as its pumping out the water.
what does make a dishwasher recirculating pump a lot quieter than a Washing machine pump? - is it the impeller? - both pumps are brushless are nt they?
