I had the same problem. 380 was running on its front wheel waving its tail in the water.
The cause was the o-ring number 31 on parts diagram was passing water and insufficient flow decreased suction. That's why polaris was not sucked down to the pool floor. The solution was to disassemble the 380, re-seat the o-ring and to re-assemble it.

Also I noticed the wheels on 380 weren't spinning well. That was caused as part number 2 got deformed from age and was rubbing on the turbine wheel 19. A solution was to scrape off some plastic from part 2 where it was in contact with the turbine.

After reassembly and adjusting the nozzle number 21 to the 11 o'clock position the 380 started running well.

Look for a stuck float switch. unit fills with water for 1 minute, then the board "looks" at the float to "see" if there is enough water in the unit to run. If float switch is stuck down, it tells the unit there is not enough water and the unit stays in the fill cycle causing the sump to overflow and send water down the drain constantly. Compressor will not run till the board senses that there is enough water to run.

My zzr is leaking fuel at a steady rate from the hose that empties out in front of the rear wheel, there is poor response from the throttle at low revs and does not hold idle. its as if its running far too...

It is flooding. Check for a float sticking or a needle and seat sticking open. It could also have a hole in a float that is it keeping open. (The float could be full of fuel and failing to float).

Used descaler yesterday, as pump was running for along time, this am motor is running continuously.

After turning power off to unit, open unit and locate float switch. Switch may be stuck in up posistion which will cause unit to run constantly. If float switch is down than switch will need to be replaced.

My polaris runs but there is no suction. Any recommendation?

Inside the part where the bag clicks onto the large circle outlet on the top are two little valves. Sometimes these get clogged by algae. Use a thin wooden skewer to poke the algae through then replace your line hose onto the pool return. Everything should work now.

Just bought a 2003 2500hd with 48000 miles. how often are the fron wheel bearings serviced and can or should synthetic oil be used in this engine ( 8.1 ).

I wouldn't recommend using synthetic oil in an 8.1 because they are known to use 1 to 2 quarts between oil changes and its kinda of a waste of expensive oil.. I always run 10w 30w in these engines. front wheel bearings.. they are non serviceable or packable they are a sealed hub unit. Inspection is raising the vehicle to where the front wheels are off the ground and shake them top to bottom when you feel play, they are due to be replaced they usually last 100k miles or less..

The AC is on and it says it is 86 in the house and cold air is kinda blowing but it is HOT in the house.

Check outside unit to see if running if not check breakers and see if there is float switch inside the air handler inside. There is only so much you can do. Calla service tech for free estimate. Russ
