Quick Red Flashing Light on Lifter

page 21 is troubleshooting guide https://www.medicaleshop.com/pdfs/drive-medical/manual/bellavita-auto-bath-lifter-manual.pdf

I'd start with a replacement main board

The lifter is a piece of junk. The red light means its time to get another. If the lifter will not lift the handset then it's time to get another - the best thing is do not get one to start!

To clear the indicators
Press CANCEL before starting the dishwasher to clear all options
and cycles.

Please note that your hand receiver has to be off the hook when using the headset.

This is correct, additionally you can use a handset lifter accessory, such as the HL1 or HL10.

Subscribing Headset to Base:

The headset and the base unit are supplied subscribed to each other. However, if you wish to use a replacement headset with the base unit (or if you lose your connection to the base unit), then you must re-subscribe as follows:

1. Return the headset to the charging base.

2. Press and hold both the + and - buttons on the back of the charging base until the red light on the front of the base starts to flash.

3. Let go of both buttons. The red light should continue to flash.

4. Press the mute switch (black wheel on the top of the headset) straight down until a green light appears on the headset, then let go of the wheel, and the light should remain on the headset.

5. Resubscription is finished when the red light on the base is fully illuminated and the green light on the headset disappears.

6. Remove the headset from the charging base lift telephone handset/press headset button if not using a handset lifter. The headset and base should now be connected.

7. If this procedure does not resolve your issue to try a system reset.

You may need to re-subscribe the headset.

NOTE: Before re-subscribing the system make sure the IntelliStand switch (on the right side of the charging base) is in the "_" position and NOT the "=" position.
