Taco 007e orange short flash white light.

Theironmonger

Getting an orange light for about 10 seconds then flashes twice white. Does this continuously.
Tried purging the system,etc. Also pulled put pump to check for debris.
Looked for a few hours online about light display. I have found nothing at all in regards to this sequence..
The other pumps are running fine. All the pumps are new the system has only been used twice.
All the pumps worked fine on initial install last weekend. I installed ,purged air etc then ran all zones for a day.. Shut off the system and now this zone flashes and will not pump.
Thanks

A few Taco guys on here will get to the bottom of this

It's not an advertisement. The guys from Taco routinely come on this website. I've never seen that sequence myself. If you ruled out air or debris in the impeller, they would probably know best what to do.
They may even want to talk to you on the phone for additional troubleshooting and could offer a replacement.
It helps to be nice.

He's referring to @Solid_Fuel_Mans signature, he thinks he's trying to advertise for new customers on his thread! 😂🤣😂

I'm not sure what's going on.... Dont know what I said wrong. I tagged a Taco guy so he'd help or refer you to someone.

95% chance air in the zone/pump/system.

I was aware...just pointing that out to the OP. Most people tend to be a little nicer when asking for help.
I think it's air also. Just never seen the constant orange light and double white flashing.
Wouldn't be surprised if it's piped wrong.
But he is an electrician and a licensed plumber.

Good morning all... The white error light in our "e" series circs indicates extremely low power consumption caused by air or dry running. Please advise the system pressure and confirm the expansion tank pressure is correct.

Also, please advise if this circ is pumping into or away from the expansion tank.

My guess is as these were initially running well something is causing the system pressure to slowly drop and the water make up device is not making up the pressure loss (by adding more water).

Attached is our Installation and Operation manual from our web site. My direct E Mail is stetho@tacocomfort.com and cel number is 647-537-1762 in case...

Now there is good customer service!! How few there are of this quality!—NBC

Taco customer service is top notch! Looks like guesses about air are correct.

The importance of pumping away from the expansion tank is very under rated by some plumbers and techs. It absolutely makes a huge difference when commissioning a new system or refilling an existing one. I have a Venturi tee system and with pumping away and a microbubble resorber I can get all the air out without bleeding the cast iron baseboards.

Smart people actually read a post before making a reply to it. Especially before making an embarrassing reply that shows both your ignorance and temperament.

Read. Understand. Think. Reply. In that order. 😁

Can you also see the white flashing light when the pump is exceeding max head? I think that is happening to mine.

Dave H_2

@ddunn When you see the flashing white light, is there a call for the pump to be running?

@Dave H_2

It happens when the primary loop (a Taco 007e) is running in parallel with the DHW (a large grundfos).

Both are pumping away from boiler supply (also point of no pressure) and pumping around a loop and back into boiler return.

I changed the settings on my boiler to not run the primary pump during DHW calls, so it isn't happening all the time any more. But I still see it for a few seconds during switchovers as the two pumps run at the same time.

Dave H_2

Well that's your problem!, they both need to be Taco pumps!

Kidding aside, since the 007e is an ECM circ, the rotor is a permanent magnet. If the circ does not have a call or not running on its own power, but there is flow occurring in the circ, it can actually make the light quickly flash white. There is no power going to the circ but there is flow in the pipe.
It happened on my own system. I put in a 0015e3 in for the indirect but forgot the check valve. When the primary/boiler pump was running, the indirect loop was getting a little flow and caused the impeller to spin. When is spun, the magnets would make the light flash.
Freaked me out at first when I first saw it the next day, also freaked out when looking at the pump and seeing the check valve right next to it! Not installed!

I had an LG washing machine I could turn on by giving the drum a spin by hand. Kinda like having a kick start on a washing machine.

How do you like them apples?

Sounds like one pump is turning the other pump into a generator.....and it doesn't like it

I've seen the Alphas blink also when they are being spun by flow and not powered up.

I know this is an old thread, but I just had this problem today after adding a boiler cleaner to the system. Apparently enough air had entered the supply feed to cause both 007e circulators to flash orange and white.

It was a simple fix. I had to purge both return lines briefly to get the water flowing again through the boiler and the circulators. Both circulators went to solid orange quickly.

I was a little surprised that I had introduced enough air into the system to stop the water flow - but again the problem was easily resolved - thanks to the postings on this site.

By any chance, are these 007e on the return?
