Symptoms
- Blade runs dry with no visible water spray
- Cutting produces excess dust instead of a wet slurry
- Pump makes noise but no water comes out
- Blade overheats quickly
Likely causes
- CommonWater reservoir empty or too lowThe pump needs to be submerged to draw water.
- CommonPump intake clogged with tile debris or sedimentCutting debris settles in the reservoir and can clog the pump screen.
- CommonKinked or disconnected water lineA pinched or loose hose stops water from reaching the blade guard.
- PossiblePump motor failingA worn pump may run but not build enough flow.
What to do
- Unplug the saw and check the water reservoir level, refilling with clean water if low.
- Remove the pump and clean any debris or sediment from its intake screen.
- Check the water hose from the pump to the blade guard for kinks, cracks, or disconnection.
- Clean out the reservoir itself, since built-up sediment can clog the pump repeatedly.
- Reconnect everything, refill with clean water, and test the pump before making a cut.
- If the pump runs but produces little or no flow, it may need to be replaced.

When to call a pro
If a new pump still doesn't circulate water, a tool repair shop can check the internal hose routing and blade guard.
Safety
Use caution
Always unplug the saw before working near the water reservoir or pump, since water and electricity together are dangerous.
