Last night temperature in high 30s. Machine shut down 3 times after beeping for 10 seconds. Codes 5-14 and 5-15 both for low hydro oil pressure. During the beeping before shutdown had no control of controls. And after the 3rd shutdown machine ran fine for what I needed to do. Now what could be the cause. Could be low hydro oil amount? Bad pressure switch? Or something more serious?
