E32 alternating with End can indicate that Siemens has limited the spin cycle because laundry is unevenly distributed. The warning does not prove a motor fault.
An alert at the end of the program
The manufacturer documentation describes the spin cycle being interrupted when the system detects an imbalance. Check how the wash ended: wetter laundry and a clump of items provide a different context than a machine that never starts to spin.
With the cycle stopped and the door unlocked, untangle the laundry. Distribute large and small items that are suitable for the same program; a single absorbent item can be difficult to balance. Do not add load beyond the limit to compensate for it.
Deciding whether to run the spin cycle again
If the water has drained and you have corrected the distribution, use a spin cycle that is appropriate for the fabric, according to the E-Nr. manual. Do not select higher speeds to overcome the imbalance.
If it happens again with different, suitable loads, note the program, items, and vibration. Check knocks and movement if the appliance moves or bangs, and seek assistance if it repeats. Load amount and distribution expands the preparation criteria.
The final moisture level should be interpreted together with the selected program and the distribution of laundry, not as isolated proof of a fault.
