My water heater needed to be restarted and my comfort recirculation system isn't working now.I"m hoping it is just the timer. I need to reset the timer and I don't know how. I can't find my manual....


Grundfos timer and pump operate by plugging into ordinary 120V outlet.

1) If outlet has power, then dial on timer should rotate.
If dial is not rotating, then check power to outlet.

2) If outlet has power, but timer is not rotating then timer has gone bad > if grundfos pump is working but timer is not working, you can buy cheap plug-in timer and use that as the timer.

3) If outlet has power and pump is not working, then manually rotate timer dial to see if pump will start.
If pump will not start, then you need a new grundfos.
There are no repair parts for these pumps, and nobody at Fixya has reported taking Grundfos apart and repairing it.
My Grundfos pump will not come apart.

4) Following link has links to Grundfos installation manual, website, product manuals, and contact.
http://waterheatertimer.org/Water-heater-recirculation-system.html#Grundfos

5) To set timer: Grundfos timer dial has movable pins that are used to set on-off times.
When pins are pushed out, timer turns pump ON.

6) Rotate timer dial clockwise until current time lines up with arrowhead located on inner dial.
Dial rotates as time passes, and pins move a lever that turns pump on-off.

Need to find a link to the owner's manual/ repair manual for the Grundfos up10-16 b5/atlc......


Following link shows links to grundfos and grundfos manuals.
http://waterheatertimer.org/Water-heater-recirculation-system.html#Grundfos

1) My grundfos stopped working because sediment clogged the pump, and the motor slowed.
When motors slow, they get hot and burn up.
I ask my friend who rewinds motors how to fix it, he said in the old days, they rewound every motor, but today they throw valuable scrap into landfill, and then buy new motors from China.
I told him not to retire, but go to school and teach kids how to rewind motors, and then took apart the grundfos line and cleaned it out with CLR, but it never worked again.

2) If timer stops working, but pump still works, you can buy cheap plug-in timer and connect grundfos to the cheap timer

Timer not working on grundfos up-15


1) I have a link for one type of timer replacement.
Have no idea if this fits your specific model.

2) Above is only repair part I've found for grundfos, and I look for this stuff.
http://waterheatertimer.org/Water-heater-recirculation-system.html

3) You can create a work-around by plugging grundfos into inexpensive wall timer that has 3-prong outlet:

http://waterheatertimer.org/Woods-timers-and-manuals.html

4) Grundfos system is replaced when it stops working.
If you have hard water, suggest you take pump off and clean with CLR.
Same with crossover located on farthest faucet.
Once motor starts to slow, it overheats and burns out.

How to program timer?


Diagram showing timer tabs being pushed in or out to set programs:
http://waterheatertimer.org/Water-heater-recirculation-system.html#Grundfos

Grundfos illustrated installation guide
http://waterheatertimer.org/pdf/Grundfos-L-UP-TL-043-install-photos.pdf

Rotate programming ring clockwise until current time lines up with arrowhead on inner dial.
Current time must be reset after power outage.
Tabs located around programming ring control timer functions.
Each tab represents 15 minutes.
Tabs push in or out using a pen.
Tabs out = grundfos ON
Tabs in = grundfos OFF
Set manual switch to TIMER and timer program operates pump
Set manual switch to ON or OFF to override timer program

Just bought a house and it has a grundfos timer/pump attached at the hot water tank. I have no hot water and the timer doesn't turn (as I've seen other timers do). Is it supposed to turn so that the...


Grundfos is a sealed unit and not a repairable item.
The timer dial should turn.
And pins located around dial control ON-OFF functions as timer dial rotates.

Does the receptacle have power?
If receptacle has power, and Grundfos is not working, then it is broken.
Grundfos manuals for UP series pumps do not show breakdown or parts list of any kind.
http://www.us.grundfos.com/web/download.nsf/Pages

Bigger question:
Why don't you have hot water?
Is water heater functioning?
Water heater is a separate appliance from Grundfos pump.
Grundfos pump circulates hot water from tank into the lines so there is no waiting for hot water ... but hot water heater should still make hot water.
http://waterheatertimer.org/Water-heater-recirculation-system.html

Add a comment about water heater if that is also a problem.
You could have 2 problems, and water heater is main issue.

How to remove the impeller off my Type UP26-96F Grundfos circulation pump


Most of these style knock off in a counterclockwise direction. The impeller is usually threaded onto the shaft that way. A small brass drift and hammer should move it easily.
