Interference
| Possible cause
| Solution
|
Piston motor |
Dosatron does not start or stops | Piston motor does not run | Reset the piston by hand |
The pump is not vented
| Bleed the pump using the bleed button
|
The maximum flow has been exceeded | 1. Reduce flow and restart pump 2. Loosen the screw cap. Remove the piston and check that the piston rings are still in place
|
Piston motor is damaged | Return the pump to your service centre/dealer |
Dosage |
Water flows back into the concentrate tank
| Contaminated, worn or missing non-return valve parts
| Cleaning or replacing the non-return valve
|
For IE model: membrane injection module and parasol valves are damaged or limed.
| Replacing the diaphragm and valve seat
|
For IE model: lip valve and parasol valves are damaged or limed
| Descale or replace the lintel valve and valve seat
|
Water flows back into the concentrate tank
| Piston motor has stopped
| See piston engine
|
Leaky suction hose
| Replace the suction tube
|
For IE model: External injection line clogged or limed
| Descale or replace the external injection line
|
Clogged intake hose or intake filter
| Replace the suction tube
|
Piston seal missing, incorrectly assembled or worn
| Cleaning up or replacing the WL3000 version
|
Worn suction tube
| Replace
|
Dosage too low
| Air is sucked in
| 1. Check that the nuts have been sucked in from the dosing element and that they are tightened 2. Check the suction hose and clean or replace it
|
Contaminated or worn non-return valve gasket
| Reduce the flow
|
Exceedance of maximum flow (cavitation)
| Reduce the flow
|
Worn suction gasket
| Replace
|
Worn suction tube
| Replace
|
For the models IE, external injection module and T-piece injection limed or damaged
| Check the condition of the parasol valves, the diaphragm and the lip valve. If necessary, decalcify or replace
|
Leaks

Leakage at the dosing tube connection (metal ring)
| The dosing tube ring is damaged or incorrectly positioned
| Replace
|
Leakage between dosing nut and washer
| The dosing element ring is damaged, incorrectly positioned or missing
| Replace
|
Leakage between screw cap and pump housing
| Screw cover gasket is damaged, incorrectly positioned, or missing.
| Unscrew the cover, clean the gasket setting, replace the new gasket or carefully replace the old one
|
Leakage between injection module and pump housing
| Seal of the injection module is damaged, incorrectly installed, or absent
| Position correctly, clean seat of seal or replace seal
|
External leakage in case of nut on the side of the injection module
| Nut is not tightened properly, or diaphragm is damaged
| Clean the diaphragm, replace it if necessary and tighten the nut
|
