Front Hydraulic Jack Leaks Down in transit

[clsfly]

Any ideas on this problem on my 2020 Solitude 310. I have ended up tying it up so I don't rip it off going down the highway.

Its solenoid valve may have debris in it allowing oil to flow. It may just need to be cycled several times to clear it.

JACKS LOWERING DURING TRAVEL! (EMERGENCY REPAIR)

IT HAPPENED AGAIN! (RV JACK FAILURE PART 2)

This problem is still persisting, now both front jacks are going down UNDER pressure. I tied them up with paracord and it snapped the cord on both sides. So now I've resorted to a chain attached to the bracket. I've cycled them numerous times, changed the fluid with no help. I am on the road and don't know when I can get help with this. Does anyone have a schematic so I know which valve controls the front jacks?

clsfly Chuck, This link https://lippert.thinkific.com/ will take you to to LCI's online training. There is a course specific to the towable jack system. Register on the site and you can take the training. They also have PDF files for all of the system parts, installation, and troubleshooting.
Are you still working with this since July and what is Lippert Tech Support telling you?

This doesn't sound good, Chuck. (Call me Capt Obvious.)

Looking through LCI's website, the only schematic I can find is the Level-Up OCTP 5th Wheel Wiring Diagram (that link should download a copy, or go to the LCI page here: https://support.lci1.com/towable-br-...vel-up-br-octp and look for QR-092. I'm not sure if your '20 has the OneControl version (and an OCTP)? Either way the power side of the schematic will be similar.

From your post's description it reads like the pump is intermittently powering up and sending fluid through the extend ports uncommanded. Again, that's not good.

Jerry's ( ThePowells ) advice to call LCI is sound -- something is not right. Given the jacks are being powered down while towing, this should be addressed ASAP.

Instead of the chains, consider asking Lippert what's the best way to disable the pump until the system can be checked by a qualified technician. As you can see from the schematic, there's not much between the pump and the battery. I'm not sure if disconnecting the connectors on the controller board is the best option, removing the applicable line from the circuit breaker to the battery, or disconnecting power at the pump itself. This circuit is "only" 12vDC but has a high amperage draw compared to most systems in your trailer, so please proceed with caution if you're unsure. (Please call LCI ASAP!)

Please post back with the resolution.

Perhaps disconnect the pump b+ from the circuit breaker as a temporary power shutoff to the pump.

Hi Chuck,

x2 on Ted's suggestion.
If hydraulic pressure is being applied . . . remove the source of the this pressure while travelling. You might even install a switch to do this until the root cause of the problem is resolved.
