If your BWT Water Dispenser displays a low salt warning, it means the regenerative wasn't refilled in time. To resolve this, siphon off or extract the brine to the level of the sieve base before refilling the regenerative. Incorrect refilling can cause the softened water to become salty.
What does Service! mean on my BWT Rondomat Duo-DVGW 3?
If your BWT Water Dispenser displays 'Service!', it means that maintenance is required after every 500 regenerations.
What to do if my BWT Water Dispenser shows 'Service!'?
If your BWT Water Dispenser displays 'Service!', this indicates that maintenance is required after every 500 regenerations. In this case, you should contact the after sales service.
What to do if my BWT Water Dispenser display indicates low salt (low salt! date time)?
If your BWT Water Dispenser display indicates low salt (low salt! date time), it means the regenerative was not refilled in time. The brine must be siphoned off or extracted to the level of the sieve base. Only after this has been done can the regenerative be refilled. If this is done incorrectly, the softened water will be salty.
Why is my BWT Rondomat Duo-DVGW 3 Water Dispenser not supplying enough water?
If your BWT Water Dispenser isn't providing sufficient water or the flow is weak, the inlet pressure might be too low, or the compressed air pressure could be insufficient. Try increasing the inlet pressure, adjusting the pressure reducer if needed, and start a manual regeneration. Also, check the inlet pressure and initiate regeneration.
How to fix BWT Rondomat Duo-DVGW 3 Water Dispenser not supplying softened water?
If your BWT Water Dispenser isn't supplying softened or blended water, it could be due to a lack of regenerative in the salt/brine container or a power supply interruption. Refill the regenerative, wait approximately one hour, and then manually regenerate the system. Also, ensure the electrical connection is properly re-established.
What does it mean when my BWT Water Dispenser displays 'Valve defective'?
If your BWT Water Dispenser displays a message indicating that Valve 1, 2, 3, or 4 is defective, the cable to the valve block might be faulty. Check the cable to the valve block and press OK to confirm.
What does 'Elyse' mean on my BWT Rondomat Duo-DVGW 3 display?
If your BWT Water Dispenser displays 'Elyse', it indicates an electrolysis cell overcurrent. Check the cable to the valve block for short circuits and press OK to confirm.
What does it mean when my BWT Water Dispenser display indicates 'Elyse'?
If your BWT Water Dispenser displays 'Elyse', it indicates an electrolysis cell overcurrent. Check the cable to the valve block for short circuits and press OK to confirm. If the malfunction persists, contact the after-sales service staff.
How to fix a BWT Water Dispenser that isn't supplying softened water?
If your BWT Water Dispenser is not supplying softened or blended water, it might be due to no regenerative in the salt/brine container or a power supply cut off. Refill the regenerative, wait approximately 1 hour, and then regenerate manually. Also, re-establish the electrical connection.
