Not enough water pressure - Dynamo ABOVEGROUND POOL PUMP - 1.5HP -

Generally speaking, In the top control head of most washing machines, there is a water level sensor that tells the machine when the drum has enough water in it and when to start the wash cycle according to what size load it is set for. In the older washers, it was basically like a barometric pressure sensor and had a clear plastic hose connected to it. When the water in the drum put sufficient pressure on the air in the hose, it would activate the switch and start the control timer, shutting of the water and starting the wash cycle. If your washer is new enough to show error codes, it may have some other version of this sensor but it will have to have something to say when enough is enough. Look in the control head on top. Good luck.

The pressure switch shouldn't be reducing pressure unless it is smaller that the water pipe. Pressure switches in water heaters are a safety device that activate when pressure builds up above a pre-defined limit. I'm guessing that the most probable cause of low water pressure is either not enough head into the water heater (this is the height of water pipe) or not enough mains pressure. Your best bet is probably to install an inline circulation pump with a flow sensor. This will automatically detect that water is being used and turn on to boost water pressure.

Are you sure the gage is correct?

Make sure you have enough water in the tank or city water hooked up. A pump will run and suck air if the level is low. it could force water to the sink, etc, but not the shower.

Are your valves for the water pump set correctly? Remote possibility someone installed a shut-off valve between the pump and shower.

Could be the pump is getting weak/leaking internally and can't build enough pressure.

Make sure the shower head is not clogged. Remove it from the hose and try again.

The water level is controlled by a pressure switch connected to a long rubber hose that goes inside the tub. If the switch is defective or if the pressure hose is blocked the machine may under-fill.

Check also inlet hose and water pressure from the house.

E1 means a leak has been detected . Check hose connections .Or drain hose height.1E would be water pressure issue.See service manual

At a high pressure you are consuming more hot water. It sounds to me like the water heater isn't big enough for what you need. You can try turning up the heat thermostat on the water tank. If the water gets hotter you won't need as much for each shower and it will also recover faster at a higger temperature.

Water pressure makes the unit turn on and off. It will only activate on it's own when enough water pressure is present. Most likely it can be water leaking from the toilet tank into the bowl, and from the bowl into the pump. Or could also be that waste water is slowly draining back into the pump through the check valve on the discharge elbow, creating enough water pressure that it will make the unit kick on and off.

Obstruction I would say. check connection from supply, hose not folded or whatever.

Check the float switch inside the tub, it should move freely up and down.

Check the harness to the motor

Check start capacitor on the left side of the wash motor
