Usually when these motors slow down, they get hot and burn out.
You can try taking it off and cleaning with CLR, but normally when they stop working, they do not revive.
I am not sure what the warranty policy is from Taco, or if Taco has a parts list.

I think following link takes you to the Taco website:

Pumps can have noises from bearings, bushings, cavitation and excess wear on the impellor and the wear rings. It is time to take it out of service and inspect it.

1) try to go the instr. manual and go to the section troubleshooting they explain this . However if you do not have it download from .
www.manualslib.com
see this causes and fix it.God bless you
Tub Bearing If the washer is making a loud noise the tub bearing might be worn out, this is a common problem. The bearing can be replaced.
Tub Seal and Bearing Kit If the washer is making a loud noise the tub seal and bearing kit may need to be replaced. This is a common problem and the parts are relatively easy to replace.

Rear Drum with Bearing If the washer is making a loud noise the rear drum with bearing might need to be replace. On this washer the bearing is not sold separately, the entire rear drum will have to be replaced. This is a very involved repair and will require disassembling most of the washer. However, the problem is going to get worse very quickly and so either the drum and bearing will need to be replaced or the washing machine.

Bearing If the washer is making a loud noise the bearing might be worn out. As bearings wear out from friction they gradually get worse and worse until they fail. In the meantime they get louder. If the noise primarily happens during the spin cycle the bearing is likely the problem.

Drive Pulley If the washer is making a loud noise the drive pulley might be worn out, cracked, loose or bent. Remove the drive pulley and inspect it carefully. If it is damaged or defective replace it.

Pulley If the washer is making a loud noise the pump may be worn out, or something might be caught in it. Remove the pump and inspect it for debris. If it is clear and the blades spin freely the problem might be somewhere else.
U-Joint Kit If the washer is making a loud noise the U-Joint may have failed. This is the primary drive mechanism for the agitation motion in this washer. Although this is not a very difficult repair for a DIY'er with some experience, the part is expensive and so it may be worth considering a new
Motor Coupling If the washer is making a loud noise the motor coupling might have failed. The motor coupling connects the motor to the washer transmission. It is designed to fail if the washer is overloaded in order to protect both the motor and transmission.

Clutch Assembly If the washer is making a loud noise in the spin cycle, the clutch assembly might be worn out. The clutch assembly makes the connection between the transmission and the inner tub. It is designed to allow the tub to get up to the proper spin speed gradually. As the clutch wears out it may become loud during spin or just after the spin cycle finishes. The clutch is not repairable, if it is loud or not working properly it will need to be replaced.

Drive Belt If the washer is making a loud noise the drive belt might be defective. Over time the drive belt will dry out and start cracking, eventually a piece of the belt can break off resulting in a loud noise whenever the motor is running.
Transmission If the washer is making a loud noise the transmission might be worn out or defective. There are many other more likely causes for noise from a washer. If the noise turns out to be caused by the
Drain Pump If the washer is making a loud noise the drain pump might be going bad or might have something caught in it. Remove the drain pump from the washer and inspect it carefully. Look for anything that might be caught in it, a piece of wire, plastic, etc. If nothing is wrong with the pump, but it's still noisy it will have to be replaced.

Drive Motor If the washer is making a loud noise the drive motor bearings may have worn out. Washer motors are normally almost silent when they run. If the motor is run without a belt hooked up to it and it's loud it will have to be replaced.

Water Inlet Valve If the washer is noisy or loud, particularly when the washer is filling, the water inlet valve is at fault. Replace it.
transmission it may have to be replaced.

First My sister inlaw has a 3/4 recirc line. used the by pass h&c under last faucet to use cold as recircu line. Note acutal 3/4recirc is in kitchen but even thou closer to water htr. it is last for...


I don't understand everything being asked, so add a comment any time.

Problem1 is excessive electric bill.
Suspect is new 120Volt Taco recirculation pump.
Look at motor nameplate for amps and watts and HP. Taco pump is usually robust 1/3 HP which is 252 watts or same as running four 60 watt light bulbs.
If pump runs 18 hours per day x 252 watts = 4536 watts or 4.5 Kilowatts per day
Buy a kill-o-watt meter that plugs into outlet, and plug Taco pump into the meter for 48 hours.
This will give you total watts used for that time period.
1000 watts = 1 kilowatt.
Electric bill is probably 12 to 20 cents per kilowatt.
So if Taco uses 4.5 kilowatts per day, that is $.54 to $.90 per day multiplied by 30 days.
So cost is $15 to $30 per month.

Problem2 is Taco runs too long.
Taco operates either by thermostat or by timer. You choose which mode by using slide switch that is usually located under the timer dial. Set switch to TIMER to use timer, and ON to use thermostat, and off to turn TACO off.
If Taco is set for thermostatic operation, the Taco might be defective. Or there could be crossover problem at single handled faucet.
Another problem could be air in the water line: install air vent.

Fuel pump noise 2005 Buell xb9sx


That is the fuel pump doing its job of pumping. If it stops making noise, it stopped pumping, and no gas is getting into your motor. Your bike will not run without a running fuel pump. :)

When running it makes a loud continuous loud noise


Your bearing are failing. Replacing them and the seal at a local electric motor repair shop will likely cost around $50.
