Step 1: Check the Control Panel

Make sure both the 12V button and Water Pump button on your control panel are switched ON. These must be activated for the pump to function.

Step 2: Test for Water Flow

Turn on a tap inside the motorhome. If the pump is working, you should get a steady stream of water. If there’s no water flow, continue to the next steps.

Step 3: Check the Fuse for the Water Pump

Locate the fuse panel:
- Usually under the seat cushion in the rear dinette area, closest to the stove.
- In some vehicles, it may be on the front panel underneath the seat.
Find the fuse marked with a tap icon (). If this fuse is lit up, it likely needs replacing.
Pull out the fuse and visually inspect it:
- If the metal piece inside is detached or broken, it means the fuse is blown.
- Replace with a fuse of the same type and rating.

Step 4: Inspect the Water Pump Itself

Locate the pump:
- Under the cushion of the opposite bench seat, beneath a removable wooden panel.
Check the wiring:
- Ensure all wires are firmly connected.
- Look for any damaged or frayed cords.
Inspect the pump:
- If the bottom of the pump feels hot, it may be seized and could require replacement.

Step 5: Prevent Future Issues

Always switch off the Water Pump button on your control panel when not in use.
Leaving it on unnecessarily can cause the pump to overheat and fail.
