56 - Chapter 11 - Troubleshooting Windrow 2500L Operator’s Manual MY18 - REV 1
PROBLEM COMMON CAUSES COMMON SOLUTION
Chem probe is not working
or is working too slow
Air leak in the vacuum
system
Check all hose clamps and fittings are tight
Lack of pressure to venturi in
top of tank Check there are no kinked hoses and the
water pressure is about 100 PSI
Spray Nozzles
PROBLEM COMMON CAUSES COMMON SOLUTION
Streaky pattern coming from
nozzle
Nozzle tip blockages.
Check for blockages by removing the
nozzle, rinsing thoroughly with water and
cleaning with compressed air.
DO NOT clean by blowing into nozzle
with mouth.
Nozzle worn or damaged.
Visually inspect nozzle for damage or wear,
conduct a jug test if necessary.
No spray coming from nozzle
Nozzle tip blockages.
Check for blockages by removing the
nozzle, rinsing thoroughly with water and
cleaning with compressed air.
Check valve blockages.
Remove the check valve and clean as
required.
Chemical Probe
ISOLATING POSSIBLE AIR LEAKS
Step 1: Check the operation of the chemical probe.
If this will transfer water at a minimum of 30 L/min
then this part of the system is okay.
If not check for air leaks at:
• Cam lever fitting at the probe
• Hose fittings
• Venturi – the venturi can suck air (less vacuum)
where the black drop-pipe connects to the
orange venturi
• The venturi may also suck air where the ‘lay flat’
hose joins the bottom of the black PVC drop
pipe
Step 2: If probe works correctly but envirodrum will
not operate, check for air leaks in envirodrum fitting
(this must be thoroughly cleaned after each use) and
check interior pipes in the envirodrum for air leaks
or damage.
SUMMARY
Check the flow of water into venturi.
Then:
1. Check the probe only.
2. Check probe and envirodrum section.
NOTE: Tests must be done with water because
the speed of the transfer is affected by chemical
viscosities.
