Winterizing and long-term storage
If you must store your pressure washer in a location where
the temperature falls below 32ºF (0ºC), you can minimize the
chance of damage to your machine by utilizing the following
procedure:
• Disconnect all water connections.
• Turn on the machine for a few seconds until the remaining
water in the pump exits. Turn off immediately.
• Do not allow the high-pressure hose to become kinked.
• Store the machine and accessories in a room that does
not reach freezing temperatures.
• Do not store near a furnace or other sources of heat that
may dry out the pump seals.
• Operate the pressure washer with non-corrosive/non-toxic
anti-freeze, a pump saver, or a pump protector before
storing for the winter.
m
WARNING!
Before reusing, completely flush the unit
out with clear water. Anti-freeze products can damage
paintwork, so you must ensure there is no anti-freeze left in the
system before using it again.
Maintenance
m
CAUTION!
Before working on the pressure washer,
disconnect the plug from the power supply socket.
1. To ensure good performance, check and clean the water
inlet filter (Fig. 27). Remove the filter and rinse with warm
water to prevent any foreign matter from clogging the
pump (Fig. 28).

3. Remove additional debris by back flushing water through
the nozzle and spray wand. To do this, place the end of
your garden hose (with water running) to the tip of the
nozzle, pushing water and debris out of the back opening
of the nozzle and spray wand.

Questions and answers
Where is the fuse on a SunJoe SPX3000?
When under pressure water gushes from under the plastic causal where the red arrow is pointing. I've replaced the washer and it continues to leak.
Your Sun Joe SPX3000 may be leaking water from under the plastic casing due to internal hose or reservoir tank issues. Users have reported that internal hoses or the reservoir tank leak badly, preventing water from gathering properly. This issue occurs even without electricity being used. If replacing the washer did not fix the problem, the leak might be coming from an internal component that needs inspection or replacement.

The circular scrubber will not turn
The circular scrubber on the Sun Joe SPX3000 may not turn if there is low water pressure, air in the pump, or a blockage in the hose or nozzle. It could also be due to a malfunction in the attachment or insufficient flow caused by a faulty connection. Ensure all hoses are airtight, the nozzle is clean, and the water supply is adequate.

When you are looking at the back of the pressure washer with the back removed you can see that water is leaking on the left side of the aluminum housing. The pressure washer was drained and stored in a heated basement all winter. How can I replace this part and how much will it cost?
