Samsung dishwasher makes a loud buzzing sound when the water is filling. It pulses a couple times to start then is constant. It pulses again right before the wash cycle. Comes from the bottom left.


This is common. The noise is coming from the water pump. If it bothers you, you can try UNPLUGGING the washer or turn off the Circuit breaker first. Then you can remove the bottom kickplate on the front of the washer and clean around the pump. If there is a water filter scree, clean it out. Make sure there is nothing rubbing against the pump which could cause a buzz. Tighten all fittings and screws to eliminate vibration noise.

Motor pulses on full power wash


It sounds like you either have a clogged nozzle or one that is too small for your pump. At lower speeds the pump is pumping less gpm. So your unloader valve does not cycle. Then when you go to full power. The engine is running faster and pumping more gallons per minute. The nozzle is too small or clogged and so the bypass opens and closes ( surges) Try a new nozzle that is the right size for your machine.

Would a bad water pump cause a van to be making a buzzing noise even when not started?


Not necessarily It will cause it to overheat though. Test by grabbing top radiator hose (while car is cool), start and feel for coolant flow pulsing through the hose. Pulse means pump is working.

1986 pontiac fiero won't start, changed fuel pump and relay gas coming up, but no spray from injectors


Actually the injectors don't spray "all the time". They pulse open for a few milliseconds then close every time they are grounded by the ECM. The distributor has a pick-up coil (Variable Reluctance sensor) that provides an A/C (Alternating Current) pulse every 120 degrees of crankshaft revolution to the Ignition Control Module also contained inside the distributor. The I.C.M. amplifies, rectifies and passes along the pules as a +12V square wave to the ECM. The ECM uses these pulses to calculate RPM and determine when the engine is rotating vs. stopped. Together with this information and more from Coolant Temp., Throttle Position, Manifold Pressure and Air Temp. the computer constantly 'looks up' what the appropriate amount of time it should pulse the injectors for to deliver the required amount of fuel.
With that in mind, the injectors are supplied with +12V via a 3 AMP fuse labeled INJ 1 for 1 bank of 3 injectors, and INJ 2 for the 2nd bank of injectors. Make sure your injectors are getting +12V whenever the key is ON or they wont fire (or at least 3 won't).
If all 6 injectors have +12V and you have fuel pressure (checked by pushing down in the center of the Schrader (tire valve stem looking thing) valve and fuel SPRAYING out, and your still not getting fuel it is probably because the injectors aren't pulsing. They are probably not pulsing because the ECM is not receiving any reference pulses from the distributor. If you have spark then you are producing reference pulses.
I hope some of this explained from an actual '86 Fiero GT 2.8L V6 owner/mechanic will help narrow down your problem.

Saniplus draining in pulses


When you flush the toilet, the Saniplus will turn on and off once or twice, this is normal. If it turns on 3 times or more then could be a problem with venting or the discharge pipe installation may not be properly installed. But when you run the sink or shower it will turn on and off constantly, this is normal. The Saniplus pumps out the water as it comes in.

Lower arm spinning slow/intermittent


running with the door open indicates another fault that could be dangerous unless you have bridged the catch for testing only, water should flow fast and forceful at all times that it circulates, through both spray arms at once, you have to look for blockages in the system, is the waste outlet pipe high enough, this allows the machine to fill adequately so it doesn't pump intermittently, i doubt very much this is an electrical problem hope i have helped a little
