Plenty of SHE33T55UC dishwashers are still running, and the reason lies in how they deal with food. Bosch never fitted a food grinder to this line, which leaves no macerator to wear out. Everything relies on a filter that the owner twists out and rinses. It is an entry-level T-generation unit in stainless, 15 place settings in a tub 23 3/4 inches deep, drying by condensation. Bosch’s own listing gives no sound rating.
The difference between a healthy one and a troubled one is household habit. Homes that rinsed the filter regularly kept a working dishwasher, while homes that never did are the ones that phone us about drain codes.
Opening up a neglected unit, we usually meet a sump packed hard, a drain pump impeller chewed by debris that slipped past a loose filter, and a heater coated with scale, which gives lukewarm final rinses and damp dishes.
It runs quieter and is gentler on glassware, but the filter now does the work a grinder once did. Rinsing that filter monthly is the habit that keeps the machine in good health.
Usually not. We clear the sump, inspect the filter stack for damage and check the drain pump for anything that slipped through. Most units recover well after that cleaning.
Monthly is a good rhythm for a household that runs the machine daily. Twist the filter stack out, rinse it under the tap, and make sure it is seated fully when you put it back.
