superbus Report post Posted August 17 (edited) While they are not especially fast at getting back with you, HWH Tech Support has helped resolve my issues each time I have called them. If it's a headscratcher you can't figure out, try giving them a call if you have a few weeks to get resolution. They have some schematics on their site which would be a good place to start if you need to get it fixed now. Basis of the issue you're having seems to be pressure related, since it starts to lift the coach but when the load ramps up it runs out of steam. Not sure if your system has a high-pressure relief valve, if so, it could be a culprit. Edited August 17 by superbus Share this post Link to post Share on other sites

rayin Report post Posted August 18 Have drive engine running or be plugged into shore power. HWH leveling systems require 13+ VDC to operate properly. Fluid reservoir should be full to within 1" of top when jacks and slide rooms are retracted.. DO NOT use hydraulic oil,, it will cause expensive problems, only use what's specified in the operator manual; which most likely is HWH oil or Dextron III ATF..

You probably did but leave your info with them in the queue. They normally call back sooner. It's pathetic really, I have no idea why it takes them so long. After my last tech call, I dealt with three different people, so it doesn't seem to be a manpower issue. Good luck and please let us all know what you find out as the root cause.

chuckconnie Report post Posted October 7 The problem was the shuttle valve on the pump unit. Works fine now. Share this post Link to post Share on other sites
