TROUBLESHOOTING

 
C-Dax Ltd and their distributors have a comprehensive parts inventory and capable service staff.  
Repairs should only be undertaken by C-Dax, or an authorised C-Dax service center. 
 

Symptom 

Possible causes (procedure) 

Probable solution 

Pump does nothing 

(makes no noise) 

Blown fuse (check wiring for shorting 
and inspect fuse) 

Repair/replace faulty wiring or 15A fuse as 
necessary 

Loose/intermittent connection (check 
all wiring and connections) 

Check all wiring and connectors to ensure solid 
connection 

On/Off switch failed (remove switch 
from handle bar, bridge the 2 spade 
terminals using a screw driver) 

Replace switch if using the screw driver causes 
pump to work 

If all above fails, likely cause is pump 
failure 

Take in to local dealer or send to C-Dax for repair. 
Be sure to include sufficient paperwork detailing the 
problem. 

Pump runs for few 

seconds then stops 

Pump has primed and pressure 
switch has activated (this is normal) 

No fault, squeeze spray trigger and use as per usual 

Fluid leaks from drain 

holes in pump 

Internal leak within pump head 

Take in to local dealer or send to C-Dax for repair. 
Be sure to include sufficient paperwork detailing the 
problem. 

Tank empties from 

one leg only 

One of the filter valves are not sealing 
off properly (Inspect the filter valve at 
the base of each leg) 

1. Unscrew the nut that holds the filter valve on to the 
bottom of the leg. Clean filter thoroughly but carefully 
using hose. 
2. Check the hose that connects to the filter valve for 
splits at bottom. If split found: replace hose. 
3. If all above fails, replace filter valve(s) 

Tank only partially 

empties 

One of the internal suction hoses has 
developed a leak. 

Remove lid and inspect internal suction hoses. The 
split/hole will be at the same level as the fluid. You 
may need to detach the hoses from the black cross-
fitting at the top of the tank and extract by removing 
the filter valve at the bottom of the leg (be sure to 
empty tank first). 

Pump runs but does 

not spray (or sprays 

but with little 

pressure) 

Air lock in pump 

Operate spray gun trigger until all air is expelled from 
the pump and hose (may take a few moments) 

Air leak in suction line 

Inspect the suction line (between the tank and pump) 
for signs of split hoses and loose clamps. Replace 
split hose if required and ensure all clamps are done 
up tight. 

Blocked suction filter valves 

Inspect filter valves and clean if necessary 

Air lock in suction line 

Pop up the blue/white vacuum release valve on top 
of the tank and press it down again (ensure this 
valve is screwed on to the black fitting tightly). 

Dirt or spray residue in pump valves 

Replace valves inside pump 

Pump fails to prime (usually on very 
first use) 

Remove the blue/white vacuum release valve on top 
of the tank by carefully unwinding it from the black 
fitting (ensure the black fitting stays attached to the 
tank). Now force water (from a garden hose) down 
the black fitting while the pump is running, this 
should force the pump to prime. Screw the 
blue/white vacuum release valve back on to the 
black fitting tightly and pop the valve down. This 
should prime the pump and make the sprayer 
operate as per normal. 

Pump sprays but does 
not stop spraying 

Spray gun trigger open 

No fault, close trigger
