Alfen Eve Single PCB Out Of Warranty Repair

Alfen Charger Faulty Out of Warranty? Don't Replace It.

If your Alfen Eve Single charger is past its manufacturer warranty, a hardware failure usually results in an expensive recommendation to replace the complete charger assembly or purchase a brand-new main power board costing hundreds of pounds.

We offer a faster, cost-effective, eco-friendly alternative. By sending just the rear power module / main circuit board to our bench, we can diagnose and rebuild the high-voltage power switching and internal sensing circuitry, saving you money and getting your charger back online quickly.

Alfen Charger Board Repair - £139 + shipping

Specialising in component-level repair and service of out-of-warranty EV charging hardware, WSMFix can help get your Alfen Eve Single operational again. I repair these circuit boards via mail-in or local drop-off near Marine Lake in Weston-super-Mare, offering a fast turnaround so you can get back to charging. This service is significantly cheaper than replacing the unit or buying full manufacturer sub-assemblies.

Common Alfen Eve Single Fault Symptoms

Is your Alfen unit displaying any of the following error codes or behaviors?

  • Error 102 – Power Switch Fault
  • Error 104 – Internal Supply / Power Circuit Fault
  • Red LED Ring or Error Screen on Boot
  • Charger detects the vehicle but fails to initiate power transfer

These issues are typically caused by failures in the internal heavy-duty power switching module or the high-voltage feedback sensing circuit on the main power board. Because these components handle intense current loads during everyday charging cycles, thermal strain over time can degrade the switching paths or cause sensing mismatches that trigger automatic safety shutdowns. My repair process rebuilds the main power switching hardware, restores degraded circuit tracks, and refreshes the internal voltage monitoring systems.

Once repaired, the board undergoes a complete diagnostic run on a dedicated bench testing rig, simulating full charging states A, B, and C along with Control Pilot verification to ensure a seamless self-clearing boot cycle when reinstalled.

EV Charger board repair - No Fix, No Fee. Book in via my contact system, send me the PCB, and only pay when the hardware is fully repaired.

Other Alfen Eve Single Faults Addressed

Besides power switching faults, I also repair other common component-level failures on Alfen power assemblies:

Complete Power Failure / Dead Unit

The unit shows no screen, no LED indication, and appears totally non-responsive. This is generally linked to failure in the primary auxiliary power supply on the rear circuit board. I rebuild this supply section to restore logic power without needing a replacement board.

Physical & Terminal Heat Damage

High current throughput can lead to loose terminal connections, terminal block burnout, or heat-damaged board traces. I professionally replace damaged power connectors and rebuild heavy copper traces to restore high-current safety.

Vehicle Connection & Pilot Signal Issues

If the vehicle fails to handshake or drops the session during initialization, the issue often stems from degraded signal components on the Control Pilot feedback network. Every repaired board is bench-tested against vehicle communication standards prior to return.

How the Process Works

I have streamlined the mail-in repair process to keep downtime to a minimum:

  • Get in Touch: Message me to discuss the error codes and book your repair.
  • Send Your Board: Carefully remove and pack the rear main board/power module, then ship it to my bench (or drop it off in Weston-super-Mare).
  • Component Repair: I rebuild the faulty switching, power supply, or sensing circuits and run full diagnostic checks on my test rig.
  • Plug-and-Play Return: Pay your invoice once fixed, and receive your board back via tracked delivery. Once reinstalled, the charger's automated self-check will clear the fault on power-up.

About

I have nearly 40 years of experience in electronics and electrical engineering. When not working on domestic items, I work in the entertainment industry maintaining and repairing specialist lighting and sound equipment for concerts and other shows. I specialise in fixing things at component level, meaning diagnosis and replacement of individual faulty parts on a printed circuit board (PCB). Often working without schematics, I trace faults using a range of diagnostic techniques and use soldering and rework methods to replace all kinds of electronic components.

My main goal is to promote a repair and re-use culture and give people the opportunity to have their electronic and electrical items repaired rather than having to throw good things away. Because of this, I also volunteer as a repairer at a local Repair Cafe in Weston-Super-Mare.
