⚠️ SAFETY WARNING: The appliance operates at mains voltage (230V). Strictly disconnect the power plug before performing any disassembly tests or checks on the swivel joint wiring. ReeFix provides this diagnostic report EXCLUSIVELY for educational and informational purposes.
TECHNICAL CHECKLIST
- Swivel movement test (Key signal): Turn on the vacuum cleaner and tilt the handle forward and backward. If the roller starts or stops depending on the angle, the copper strands inside the swivel joint housing are severed due to mechanical fatigue.
- Roller mechanical-structural check: With the plug disconnected, manually turn the bristle roller. If it offers strong resistance, check for tangled threads or hair around the side bushings.
- VK135/VK136 body voltage check: Use a multimeter to measure voltage on the bayonet connector pins to rule out a fault in the main body switch.
- Swivel joint inspection: Remove the swivel joint screws (requires Torx screwdrivers) and check the condition of the PVC/silicone sleeve in the cable grommet.
Often happens when: continuous use with tight turns causes small-radius bending of the electrical wires against the ABS plastic ridges, leading to copper breakage from repeated torsional stress.
INSPECTION RESULT
1. Severed conductors in the swivel joint (75% of cases)
- Clinical sign: Intermittent operation when moving the handle/sleeve, definitive roller lockup.
- Action: Repair wiring or replace component.
- Components: Vorwerk Folletto EB350 EB351 EB360 swivel joint electrical wiring cable (€12–€20) or Vorwerk Folletto EB350 EB351 EB360 complete articulated joint (€20–€30).
- DIY Feasibility: Medium (requires dexterity in routing cables correctly without pinching them).
2. Roller jammed by debris or seized bearings (15% of cases)
- Clinical sign: Overheating of the brush housing, straining noise from the auxiliary motor before stopping.
- Action: Cleaning and lubrication or replacement Vorwerk Folletto EB350 EB351 replacement brush roller (€10–€18).
- DIY Feasibility: High.
3. No voltage at bayonet socket (7% of cases)
- Clinical sign: No motorized accessory activates when connected to the Folletto VK135/VK136.
- Action: Repair motor body contacts (specialized technical service, €30–€50).
4. Auxiliary motor winding or board interruption (3% of cases)
- Clinical sign: Wiring intact, roller free, voltage present but no rotation.
- Action: Replacement of internal motor or entire motorized brush.
TOOLS NEEDED FOR ANALYSIS
SUMMARY REPORT FOR THE TECHNICIAN
"EB350/EB351 brush roller not rotating on VK135/VK136. Roller mechanically free. Check continuity of internal wiring in the ball joint and potential wear of flexible conductors in the ABS grommet."
If the continuity test on the joint cable fails -> replace wiring or joint (€12–€30, DIY alone); otherwise check 230V voltage on the VK135/VK136 connector.
