And that is what happens when the previous owner forgets to run really hot detergent/bleach washes monthly or so, forgets to clean the pump and perhaps uses cold washes.
And its why we wash at least 100ºF for our clothes. When I run the machine, clothes are washed at around 120º - to keep the machine cleaner (and we use Water-Plus to increase the water and add 1 rinse to the 2 rinses).
Looks like a LOVELY machine though. Love the colour of that control panel!
