Frequently Asked Questions - WS 50 Kärcher

How to install the Kärcher WS 50 water softener?

Place the device on a flat and stable surface. Connect the raw water inlet (mains water) and the soft water outlet to the consumers. Open the water supply and bleed the system by opening the bleed valve until no more air escapes. Observe water pressure between 2 and 6 bar and a temperature of 5°C to 30°C.

How to regenerate the resin?

There are two options: if you have the WS regenerator, connect the unit to the regenerator and follow its manual. Otherwise, replace the resin in the tank (exchanger) by emptying the old resin and pouring new resin (ref. 6.761-031.0) - 12.5 liters for the WS 50. Then fill the tank with water and reassemble the unit.

What is the production capacity depending on water hardness?

The capacity varies according to the raw water hardness. For example, at 5 °dH, the capacity is 10 m³; at 10 °dH, 5 m³; at 20 °dH, 2.5 m³. Consult the table in the manual for intermediate values. The volumetric meter displays the volume of soft water produced.

How to drain the device in case of frost risk?

Remove the hose between the filter and the tank and let the tank drain. Open and empty the filter. Remove the hose at the soft water connection. Tilt the unit onto the transport rails and open the drain valve on the hose. Make sure the water has completely drained before winterizing the installation.

What to do in case of a leak?

First check that the connection adapter is properly tightened with a wrench. If the leak persists, inspect the seals and replace them if necessary. Make sure all connections are watertight. If in doubt, contact customer service.

How to replace the resin?

Depressurize the installation. Remove the hoses, loosen the tensioner and remove the unit from the frame. Unscrew the tank adapter and remove the riser tube. Tilt the tank to collect the old resin. Rinse the tank with water, then pour in the new resin (12.5 liters for WS 50) using a funnel. Fill with water, reinsert the riser tube making sure it is centered, then reassemble the installation.

What type of battery for the display?

The dial volumetric meter uses a CR2032 battery. Regularly check the battery level displayed on the screen and replace it if necessary.

Is the treated water drinkable?

No, the water softened by this device must not be used for the production of drinking water. It is exclusively intended for technical uses, such as cleaning or supplying machines. The device is not compliant with drinking water standards.

How to clean the filter?

Check the filter cartridge daily for clogging. If it is clogged, replace it with a new one (ref. 6.761-361.0). For the prefilter, use the supplied wrench to disassemble and clean it. Make sure the device is depressurized before any intervention.

What to do if the device does not produce soft water?

First check if the installation is exhausted: if you have a WS regenerator, regenerate the installation. Otherwise, replace the resin. Also check the condition of the lower filter nozzle on the riser tube: if it is defective, replace it. Make sure all connections are correct and the water supply is open.

General instructions

Intended use:

Hard water

Untreated water, mainly tap water, municipal water, or well water.

Soft water

Due to the water softening unit, the water does not contain hardness salts, such as calcium and magnesium salts.

Brine tank

Also called "brine reservoir". It contains a saline solution used for softening.

Saline solution

The material that softens in the brine tank reservoir, thanks to which water softening occurs.

Regeneration

Regeneration of the saline solution is carried out by rinsing with a solution of table salt. For this, a regenerator is needed.
