Risk level

High

Professional inspection is recommended.

Urgency

High

Quick answer

Your control unit cannot be charged. The charging voltage at the USB port on the control unit is too low. This means that charging is not possible. For 144000, Bosch's user step is: Please use a different power bank or a different charger to charge the control unit via the USB port. If the same code returns, preserve the display and stop repeating resets.

Safety first

Stop and check this first

  • Do not open the battery, drive unit, display, remote or charger and do not probe contacts. Stop for moisture, damaged cables, sparks, swelling, burning smell or repeated shutdown.

Safe checks you can perform

  • Preserve the code before changing anything
  • Apply only Bosch's published user step
  • Use recurrence as the stop point

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Measured handoff for 144000

What a technician must be able to justify

A technician is coming

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Measured handoff for 144000

    What they doUse the saved timing, system generation and Bosch diagnostics to test Control unit in the state that produced 144000; verify software, connectors and component values before replacement.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Checks and evidence, step by step

Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. 1

    Preserve the code before changing anything

    No special tools

    Procedure

    Photograph 144000. Record the eBike model, Bosch system generation if known, battery level, Control unit, what stopped working and when the code appeared.

    Do not open the battery, drive unit, display, remote or charger and do not probe contacts. Stop for moisture, damaged cables, sparks, swelling, burning smell or repeated shutdown.

    Evidence: Bosch eBike Systems — official fault code 144000

  2. 2

    Apply only Bosch's published user step

    No special tools

    Procedure

    Please use a different power bank or a different charger to charge the control unit via the USB port. Record whether the condition “Your control unit cannot be charged.” disappears and whether 144000 reappears after the exact published step. Do not add an undocumented reset or open a component.

    Do not open the battery, drive unit, display, remote or charger and do not probe contacts. Stop for moisture, damaged cables, sparks, swelling, burning smell or repeated shutdown.

    Evidence: Bosch eBike Systems — official fault code 144000

  3. 3

    Use recurrence as the stop point

    No special tools

    Procedure

    If 144000 remains absent, monitor the same function; that does not prove a repair. If “Your control unit cannot be charged.” or 144000 returns, stop the user checks and book a Bosch eBike specialist.

    Do not open the battery, drive unit, display, remote or charger and do not probe contacts. Stop for moisture, damaged cables, sparks, swelling, burning smell or repeated shutdown.

Symptoms and causes

Probable causes · in order

  • What the code establishesConfirmed

    Bosch identifies 144000 at Control unit: Your control unit cannot be charged. Keep that meaning scoped to a Bosch eBike system and the exact code shown.

    Evidence: Bosch eBike Systems — official fault code 144000

  • What the official step decidesPossible

    If “Your control unit cannot be charged.” clears after Bosch's exact step, only the current condition has cleared; no failed part has been proved. If 144000 returns, the documented user branch is exhausted and the recurrence becomes the evidence for service.
