Overview

A dehumidifier draws air across a cold coil, condenses the moisture out of it and drains it away. That is how a building actually dries — fans on their own only move damp air from one place to another.

Water damage restoration, drying out buildings after floods and leaks, preventing mold in damp spaces, and drying new plaster, paint or concrete.

Close the doors and windows. Left open, the machine is trying to dry the outdoors, and in this climate it will not win.

Run the drain hose downhill to a drain, or use the built-in condensate pump. A full tank stops the machine, usually overnight when nobody is there to empty it.

Troubleshooting

Running but not collecting water

Checks to try, in order

  1. Clean the air filter.
  2. The room may already be dry, or too cool — performance drops in cool rooms.
  3. Ice on the coils? Let it run a defrost cycle or switch off to thaw.

Reference draft — always follow the manufacturer’s manual.

Leaking water

Checks to try, in order

  1. Straighten kinks in the drain hose.
  2. Check the condensate pump outlet isn't blocked.

Reference draft — always follow the manufacturer’s manual.

Fan runs but compressor won't start

Checks to try, in order

  1. Wait a few minutes — many units delay the compressor after being switched off and on.

Reference draft — always follow the manufacturer’s manual.

Tool won't switch onShared · Electric (corded)

Likely causes

  • Tripped GFCI or breaker
  • Lock-off button
  • Damaged cord
  • Dead outlet

Checks to try, in order

  1. Check the outlet works and reset any GFCI / RCD that has tripped.
  2. Release the lock-off button or safety switch before squeezing the trigger.
  3. Inspect the cord and extension lead for cuts, crushed sections or damaged plugs.
  4. If running from a generator, make sure it's running and its breaker hasn't tripped.

A damaged cord or plug means the tool is out of service. Tag it and return it — never tape a cord.

Reference draft — always follow the manufacturer’s manual.

Keeps tripping the breakerShared · Electric (corded)

Likely causes

  • Circuit overloaded
  • Undersized extension cord
  • Blunt accessory

Checks to try, in order

  1. Plug into a circuit with nothing else heavy running on it.
  2. Use a shorter, heavier extension cord. Long, thin cords starve the motor and trip breakers.
  3. Don't force the tool — a dull bit, blade or disc makes the motor draw more current.

Reference draft — always follow the manufacturer’s manual.

Overheating, burning smell or heavy sparkingShared · Electric (corded)

Checks to try, in order

  1. Stop and unplug the tool.
  2. Check the motor vents aren't blocked with dust.
  3. Let it cool, fit a sharp accessory and let the tool's weight do the work.

Heavy sparking from the vents or a burning smell that returns points to worn brushes or a failing motor — workshop only.

Reference draft — always follow the manufacturer’s manual.

Safety

For electric (corded)

  • Inspect the cord and plug before every use. Use a GFCI/RCD outdoors or near water.
  • Unplug before changing blades, bits, discs or pads.
  • Wear eye protection, and a dust mask when cutting, grinding or sanding masonry.
