Answer to continue safely
Is it safe to keep using?
Maybe. The dishwasher will continue to run cycles with nE present, but washing performance will be significantly degraded as water cannot be properly distributed between zones. Run the machine only if necessary until the Vario motor is repaired.
Can I reset the code?
Yes. A power reset may clear a transient nE fault. If the error returns during the next cycle, the Vario motor or its wiring requires physical diagnosis and likely replacement.
When to stop immediately?
Stop if you notice: nE returns on every cycle immediately after a power reset, confirming hardware failure that will not self-resolve., Loud grinding from the sump area continues throughout the cycle, risking damage to the motor housing or adjacent components..
Symptoms You May Notice
Dishes on one rack level consistently come out dirty
Because the Vario motor is stuck in one position, water is directed only to one zone — dishes in the zone not receiving water will remain unwashed or poorly rinsed regardless of cycle selection.
Unusual grinding or clicking from the sump area during the cycle
A jammed or failing Vario motor may produce grinding, buzzing, or clicking sounds from beneath the spray arm assembly as it attempts to rotate against an obstruction.
nE code displayed and cycle aborted mid-wash
The control board detects no position feedback from the Vario motor after commanding it to switch zones, halts the cycle, and displays nE to identify the faulty component.
No water pressure from the upper spray arm despite lower arm working
If the Vario motor is stuck routing water only to the lower zone, the upper spray arm receives little or no water pressure, leaving upper-rack items unwashed while lower-rack items clean normally.
Possible Causes
Failed Vario motor
The motor's internal windings, brushes, or gear mechanism have failed, preventing it from rotating to switch water flow between spray zones.
Requires ProfessionalForeign object jamming the Vario motor
Small debris — broken glass, food stones, or plastic fragments — that fall through the filter area can lodge in the Vario motor housing and physically block its rotation.
DIY PossibleWiring harness fault to Vario motor
A loose, corroded, or broken wire in the harness connecting the Vario motor to the control board prevents the motor from receiving commands or sending position feedback.
Requires ProfessionalSafe Checks You Can Do
-
1
Power reset the dishwasher
Turn off the dishwasher, unplug it or turn off its circuit breaker, and wait 5 minutes before restoring power. A transient motor control error can sometimes clear with a full reset — restart a cycle and observe whether nE reappears.
-
2
Clean the filter and sump area
Remove the lower rack, twist out the cylindrical filter, and remove the flat mesh filter beneath it. Clean both thoroughly under running water and inspect the sump cavity beneath for glass chips, seeds, or small objects that could have entered the Vario motor area.
-
3
Inspect the spray arm ports for blockage
Remove the lower and upper spray arms by unscrewing the central caps. Rinse the arms and use a toothpick to clear any blocked spray holes. Reinstall both arms ensuring they spin freely by hand before running a test cycle.
When to Call a Professional
Contact a qualified technician if:
- Resistance test of the Vario motor windings shows an open circuit or values outside the specified range, confirming motor failure.
- The Vario motor housing is cracked or shows signs of water intrusion causing internal corrosion.
- A replacement Vario motor is installed but nE persists, indicating the control board's motor drive circuit has failed.
