HWH Hydraulic Stairs and Jacks

[Miked2145]

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.

it is good practice to close steps before dumping the air bags.



Newmar has an option were they can add a switch to disconnect the sensor and another to reset the HWH pump and system. mainly for when the step sensors go bad, you can use the one switch to disconnect the step sensors, and the second one will help to reset the hwh, and you'll be up and running.

Newmar has a recall on the HWH steps under warranty. they add a switch next to the front door to disconnect the sensors and drop the steps, and a reset button for the HWH pump and system which is just like pulling the fuse in the outside fuse box. We had it done at the factory last month.

Good luck its a pain when the HWH is not work correctly,
