How do you hook up a haywood viper to the pool to vaccuum

error code is SF. temp sensor failure

recheck your connections and make sure you do not have your wires crossed

Make sure that your shoes and wings are installed properly and not worn. This is the most common issue with these pool cleaners. Improper water flow could also be the problem. Check with the water flow gauge. Make sure there is no blockage in the cleaner's throat and that there is proper tension in the rear flap.

If you have replaced the parts on your pool cleaner, it is probably going to be an issue with the water flow. Check the water flow with your waterflow gauge and adjust it if necessary. See step 6 in the owners manual below if you are not sure how to adjust your water flow.

Nope.... just replace the motor.... Some shops will redo bearings, but usually a 30 day warranty and a long wait.. Walk out the door with a new one with usually a 1 year warranty...

Could have air in your vacume hose line. Make sure vacume hose is full of water before hooking it up

Check to see if the plastic ball is stuck . There should be a ball under the motor , make sure it moves freely. Make sure your vacum lines are not plugged . Best of luck Ed.
