E07 — Motor Control / Electronic Fault

E07 is not in Bosch's official US dryer error-code list (which only documents E01/E02 as a pair, E06, and an E08/E09/E24/E25/E28/E90 electronics group — note that E09 is documented as a generic 'electronics fault,' not specifically a compressor fault). The 'motor control / electronic fault' explanation below is not confirmed on Bosch's US consumer page — verify against your model's manual.

How to fix it

  1. Unplug the dryer and allow 10 minutes for capacitors to discharge.
  2. Remove the kickplate and inspect the evaporator/condenser fins behind the condenser unit — vacuum gently with a soft brush.
  3. Verify the condenser unit and lint filters are clean.
  4. Listen at startup — humming with no compressor run suggests capacitor or start relay failure.
  5. Test the compressor start capacitor with a meter; replace if out of spec.
  6. If refrigerant leak is suspected (oily residue, no cooling at evaporator), call a certified appliance tech — sealed system work is not DIY.
  7. If compressor windings test open or shorted, schedule a service call — heat-pump compressor replacement is professional-only.
  8. Document model and serial before contacting Bosch service — many heat-pump dryers have extended sealed-system warranties.

Why it happens

Typical signs: No heat on heat-pump model · Clothes cold at end of long cycle · Clicking sound from base of dryer · Cycle ends prematurely

  • Compressor start capacitor failed Compressor hums but can't start; capacitor is a common wear item.
  • Compressor overload tripped Internal klixon trips on overcurrent — often due to refrigerant or ventilation issues.
  • Refrigerant leak in sealed system Loss of refrigerant — requires sealed-system repair by certified tech.
  • Restricted airflow over evaporator/condenser Dust/lint buildup on heat-exchange fins causes high-pressure trip.
  • Failed inverter or compressor relay on control board Electronics that drive the compressor have failed.

Frequently asked questions

What does the E07 code mean on a Bosch dryer?

E07 is not in Bosch's official US dryer error-code list (which only documents E01/E02 as a pair, E06, and an E08/E09/E24/E25/E28/E90 electronics group — note that E09 is documented as a generic 'electronics fault,' not specifically a compressor fault).

What causes the E07 code on a Bosch dryer?

Compressor start capacitor failed: Compressor hums but can't start; capacitor is a common wear item. Compressor overload tripped: Internal klixon trips on overcurrent — often due to refrigerant or ventilation issues. Refrigerant leak in sealed system: Loss of refrigerant — requires sealed-system repair by certified tech.

Is it safe to keep using a Bosch dryer with a E07 error?

Limited use only. This is rated a serious-severity fault.

How do I fix E07 on a Bosch dryer?

Unplug the dryer and allow 10 minutes for capacitors to discharge. Remove the kickplate and inspect the evaporator/condenser fins behind the condenser unit — vacuum gently with a soft brush. Verify the condenser unit and lint filters are clean.
