If a Bosch WAT28400UC did not spin and the laundry is still wet, Bosch's table lists the causes: the load size is too small (add more laundry), large items became entangled in the drum and could not be distributed by the Unbalanced Load Detection system so the spin was cancelled for safety (always mix large and small items), excessive suds from too much or non-HE detergent (the foam symbol shows), or No Spin was selected (select a spin speed of Low, Med or High). The message E:32 alternates with END: it is not a fault; the unbalanced load detection interrupted the spin because the laundry is unevenly distributed, so distribute items evenly and start an additional spin program. Repeated spinning with Wash flashing means the system is balancing.

Before you touch a setting
Record this first — changing settings destroys the evidence
- Whether E:32 with END showed on the display
- The spin speed that you selected
- How big the load was that you washed
Try in this order
0 of 5 completedCheck the spin setting
ReversibleCheck the spin setting, since No Spin leaves the load saturated, so choose Low, Med or High.
Add or mix laundry
ReversibleAdd or mix laundry, since a small load will not spin, so mix large and small items.
Run an extra spin
ReversibleIf E:32 alternates with END, distribute the items evenly and start an extra spin program.
Cut the suds
ReversibleCut the suds, by using less HE detergent, and run a rinse, and then test again to see whether it helped.
Clean the pump
ReversibleClean the pump, and if water remains, clean the drain pump, and then test again to see whether it helped.
Model-specific
What is true of this model and not of its siblings
- Unbalanced load detection
- Bosch describes the Unbalanced Load Detection system as spinning the laundry several times to ensure even distribution, which adds time; with a small or entangled load it may cancel the spin. Its own guidance is to always load a mixture of large and small items, which are easier to distribute in the drum, and to add more laundry if the load is too small.
- Drum suspension
- The washer drum suspension system shifts during spinning as the speed increases, which may result in a slight shaking during the spin speed transition. Mixing small and large items minimizes it, and the machine should be level with all four feet pressing equally against the floor and with the transport bolts removed.
