Technical Analysis and Resolution

Resolving Error 52

Error 52 signals a loss of continuity or a parasitic short on the bowl pins. This often happens when spilled liquids penetrate into the lower housing. Restore functionality by cleaning with Dry Electronic Contact Cleaner Spray and check the Vorwerk Bimby TM31 Blade Gasket; if damaged, replace the Vorwerk Bimby TM31 Bowl Contacts.

Resolving Error 51

Error 51 indicates a missing signal from the lid safety circuit. A worn internal rod no longer presses the safety switch. If turning the knob does not produce a mechanical click, you must replace the Vorwerk Bimby TM31 Lid Locking Lever or the Vorwerk Bimby TM31 Microswitch. To perform an ohmic measurement, a Precision Digital Multimeter is required after opening the casing using a Tamperproof Torx Screwdriver Set.

Verification Checklist

• [ ] Disconnect the power plug from the wall socket.
• [ ] Thoroughly clean and dry the pins under the bowl using a dry contact cleaner spray.
• [ ] Inspect the condition of the blade assembly gasket to rule out leaks.
• [ ] Check for proper mechanical click of the microswitch by operating the lid lever.
• [ ] If deoxidizing the pins does not resolve Error 52 or if Error 51 persists, have a qualified technician replace the internal microswitch.
