Just Say Yes - S4-E7
Agent Lowell: That's Mallory all right. Busted twice for non-possession. Jumped bail a year ago and ran off to Mexico.
Damon: I heard he died of an under-dose.
Agent Lowell: Same here. I guess we were wrong, huh? It's a safe bet Mallory snuck back into the country to spread more of his anti-drug propaganda. A guy like that shouldn't be on the street.
Other mistake: The Sliders discover the reverse-time issue when they notice that the clock on the wall is backward. However, in other shots, clocks look normal. Look carefully at the clocks on the judge's desk as the camera pans by.
Trivia: On the equation on Quinn's chalkboard, T squared ("T2") appears in several places, a nod to Tracey Torme, Co-director of the series.
Question: Has Quinn, Wade, Rembrandt or Arturo ever found out what caused the Slider to malfunction?
Answer: It didn't malfunction. If I remember correctly, Quinn forgot to enter the coordinates to go home into the device.

The device (timer) didn't open up a vortex to their home world because they opened the vortex up too early, before the timer hit zero. They were on a frozen planet and didn't think they could survive 5 hours and Quinn didn't realise that's what his double was warning him about. The vortex expanded to engulf Rembrandt because Quinn added too much power into the vortex to allow 3 people to slide.
