Taco 007e no power

Our hot water stopped, checked the unit and it had a red light. Looked online and suggestion was power unit off and back on. Now no indicator light at all, and obviously still no hot water. Checked connection and fuses. All working.

Here are the instructions for the 007e, with trouble codes listed at the end:

The red LED indicates a blocked/stuck rotor, which means the pump would need to be disassembled. Here's more discussion of your problem. In the case below, a piece of solder probably jammed the pump.

The solid red light is also an indication of an air bound circulator. The 00e circs have SureStart built in and will try to correct either a seized impeller or an air bound casing. If it can't clear either issue, it will stop, the LED will turn solid red and wait for a technician to diagnose the issue.

When you do run into the red LED, cycle the power to reset the circ. If either of the above issues are still present, it will try all over again without damaging the circ. A white flash then back to solid orange indicates air bound. If a white then red led flash, then back to orange, indicates a seized impeller.

Correct either situation and turn back on. If there is no light, that mean there is no power at all. Check the controller and then confirm 120v at the circ
