I have almost no wiring/circuit experience. I am trying to modify a hot power washer (Sanitech Mark IV) to improve it's heat output. Our problem is that when we shut off flow (at the trigger), the propane burner turns off (as it should) but after we start spraying again it takes several seconds for it to kick back on. The result is we are not getting near as much heat as we'd like since our work flow requires frequent pauses. A flow switch kills heat instantly by opening a circuit tied to gas valve solenoid (24v). I wonder if there is any sort of "off delay" capacitor or the like that stores a bit of power that I can put in line after the flow switch so it stays "on" for a few seconds and skips the shut down process for those times when we are only closing the trigger very briefly. I think 10 seconds would be the max I would go for safety reasons. Again, I'm just trying to stop those short off-on cycles and want the heat to stay on even if water isn't flowing for 10 seconds. Linking to exact product if you know them would help alot since I'm not well versed in understanding the specs of this stuff.
