Frequently Asked Questions - WPD 50 Ws Kärcher

How to install the Kärcher WPD 50 Ws water dispenser?

Place the device on a flat, frost-free surface. Connect the water supply (pressure 1.5-6 bar) and the CO2 cylinder with the supplied pressure reducer. Plug into an outlet protected by a 30 mA circuit breaker. Leave a space of at least 100 mm at the rear. Refer to the Installation chapter of the manual for more details.

How to change the Hy-Pure-Plus filter?

Close the water supply, empty the device by pressing the 'Chilled water' button. Open the filter cover, turn the used filter counterclockwise to remove it. Insert the new filter by turning it fully clockwise. Replace the cover, open the water and rinse for 5 minutes. Wear sterile gloves to avoid contamination.

Why is the water not sparkling?

Check that the CO2 cylinder is not empty and that the pressure reducer is set to 4 bar. If the problem persists, check the condition of the filter (a dirty filter reduces flow rate). Refer to the troubleshooting table in the manual.

How to perform the semi-annual chemical cleaning?

Close the water and CO2 supply. Remove the filter and insert the service cup. Prepare the cleaning kit with 4 Bevi alkaline tablets. Connect the kit to the water inlet, open the water and start the device. Alternate between sparkling and chilled water distribution while respecting the waiting times. Rinse thoroughly until the blue coloration disappears. Refer to the Chemical cleaning chapter.

What to do if the device does not dispense water?

First check the water supply (tap open) and pressure. Make sure the device is on and the buttons are active. If the problem persists, check the fuse (6 A) behind the cover next to the main switch. In case of recurring fault, contact after-sales service.

Which CO2 cylinder to use?

Use a CO2 cylinder compliant with directive 96/77/EC (food grade). Never use a cylinder with a rising tube (identified by a red sticker). The cylinder must be equipped with the approved Kärcher pressure reducer (ref. 2.644-217.0 or 2.644-218.0 depending on type). Place it vertically and secure it with a strap.

How to maintain the drip tray?

Empty the drip tray daily when the float indicates the maximum level (red ring visible). Clean it with hot water or in the dishwasher. Do not use alcohol-based or abrasive detergents on synthetic surfaces.

Can the device be used outdoors?

No, the device must be installed indoors, in a frost-free room (ambient temperature 5-32 °C). Do not expose it to weather or direct sunlight.

What to do in case of prolonged absence (more than 4 days)?

Close the water supply, turn off the device and close the CO2 cylinder (or set the regulator to 0). Before reuse, flush 2 liters per type of water and perform a complete chemical cleaning to eliminate germs.
