KÄRCHER HDS MODEL REPAIRS

Kärcher HDS 10/20 repairs & servicing.

High-output three-phase machine used for demanding transport, agricultural and industrial cleaning. We diagnose pressure, burner, electrical and water-system faults in our Greater Manchester workshop.

Model-aware fault finding.

The Kärcher HDS 10/20 is a 400/415V three phase machine. Correct diagnosis starts with the exact model, serial number and symptoms because components and control arrangements can differ between production versions.

Typical Kärcher HDS 10/20 repair enquiries.

  • Three-phase supply, contactor or control faults
  • Pressure loss at high water flow
  • Burner cycling or combustion problems
  • Leaks from high-pressure components or the heating coil

What we test.

Water sideInlet, pump, seals, valves, pressure and flow
BurnerFuel delivery, ignition, airflow and combustion
ControlsSwitches, interlocks, contactors and shut-off
Load testHeat-up, trigger cycling and burner restart

We explain the likely repair value before unnecessary parts are fitted. Older machines can still be economical when the pump, motor, boiler and chassis provide a sound base.

Book with the right details.

Send a clear data-plate photo, the supply voltage, smoke colour if relevant, and what the machine does with the trigger open and closed. Stop using it if diesel is collecting, smoke continues after shutdown or an electrical fault repeatedly trips the supply.
