HWH Hydraulic Stairs and Jacks
Recently acquired a new 2018 Essex. We had an issue where we could not get the jacks to deploy.
Looks like the hydraulic stairs were extended and when we set the jacks to deploy, the air bags dumped and the stairs descended on to the concrete pad next to the coach and tore off the horizontal sensor which runs along the bottom of the third stair.
Confirming with HWH, they indicated the jacks will not deploy if the sensor is damaged.
Most importantly, HWH said that the jacks should not be deployed with the stairs extended. Always retract the stairs before you deploy the jacks. Lesson learned.
HWH was very generous in authorizing a warranty claim for the replacement of the sensor.
