⚠️ SAFETY WARNING: Disconnect the power plug before any intervention. Testing 230V circuits and high-power components carries severe risks of electrocution and must be conducted with appropriate protection. ReeFix provides this diagnosis EXCLUSIVELY for educational and informational purposes.
Analytical Diagnosis Bimby TM5 (Error C24/C25)
Codes C24 and C25 indicate an interruption or anomaly in the power supply chain of the 1000W mixing bowl heating element.
| Component Under Test | Expected Value / Status | Corrective Action |
| :--- | :--- | :--- |
| Bowl Heating Element | ~50 - 55 Ω between pins | Contact cleaning or bowl replacement |
| Housing Spring Contacts | Clean, unoxidized, reactive | Treatment with dry contact cleaner spray |
| Board Power Relay | Continuity upon switching (12VDC) | Desoldering and replacement of burnt relays |
Main causes:
- Burnt or stuck power relay (70%): Continuous temperature modulation wears down internal contacts.
- Cold or cracked solder joints (15%): Often happens when high-speed mixing vibrations break the relay leads on the board.
- Bowl connector oxidation (10%): Residue or deformation on the housing spring blades.
Quick Checks and Procedure:
- Deoxidize the mixing bowl housing pins with a non-residual dry electrical contact cleaner spray.
- Measure the bowl resistance (50-55 Ω) using a precision True-RMS digital multimeter.
- If the board does not switch voltage, desolder defective components using desoldering braid and a desoldering pump with a professional soldering and desoldering station to install a new Vorwerk Bimby TM5 12VDC board power relay, or consider replacing it with a complete Vorwerk Bimby TM5 power motherboard.
If the bowl resistance is correct (~50Ω) but heating fails -> replace the power relays (or the entire board); otherwise restore the bowl contacts.
