I have an Istobal M Start .
The one vertical brush is acting up.
At beginning of wash the left one comes out and rolls over front of vehicle but right one doesn’t , and when spinning down side of car it hardly touches the side.
When finished it parks back where it should normally ??
Hi, new to this forum but finding it helpful.
My LP functions, Presoak and wax are running out the gun for approx 50 seconds after being shut off.
Changed manifold and solenoids and still doing it.
I have 2 SS bays and all doing the same.
