one of life's mysteries

[ramtops]

why does a dishwasher need a cleaning cycle every now and again?

I mean, every time it's run, it has water at 70° hot, and a tablet which is basically caustic soda, and yet every now and again, the inside of the beast gets greasy, and I have to donate it a cleaning tablet and a hot wash.

all very odd.

icky filters, usually; gunk gets stuck in the filters and comes back out. the rinse cycle is aimed at the plates rather than the walls and doesn't flush it all back down?
