Narrative:
We had just landed in ZZZ from ZZZ1. On the taxi we shut down engine #2 and turned off engine anti-ice. We noticed that the #1 engine anti-ice valve did not indicate that it was open. There was an MEL requiring the #1 engine anti-ice valve to be wired open; and engine anti-ice selected to engine prior to every departure. This should result in the open indication any time the engine is running; regardless of anti-ice switch position. After we parked; we called maintenance to look at the discrepancy. We thought that it was on prior to departure; so maybe the valve did not remain wired open. Maintenance looked at the #1 engine anti-ice valve and told us that the valve had not been locked in the open position as per the MEL (30-11). They completed the procedure and we verified the valve position by starting the #1 engine. We then departed normally on our next flight with the same aircraft.

Title: A EMB145 WAS DISPATCHED WITH THE #1 ENG COWL ANTI-ICE VALVE DEFERRED OPEN PER THE MEL. SPECIAL PROC TO WIRE VALVE OPEN NOT ACCOMPLISHED.
Narrative: WE HAD JUST LANDED IN ZZZ FROM ZZZ1. ON THE TAXI WE SHUT DOWN ENG #2 AND TURNED OFF ENG ANTI-ICE. WE NOTICED THAT THE #1 ENG ANTI-ICE VALVE DID NOT INDICATE THAT IT WAS OPEN. THERE WAS AN MEL REQUIRING THE #1 ENG ANTI-ICE VALVE TO BE WIRED OPEN; AND ENG ANTI-ICE SELECTED TO ENG PRIOR TO EVERY DEP. THIS SHOULD RESULT IN THE OPEN INDICATION ANY TIME THE ENG IS RUNNING; REGARDLESS OF ANTI-ICE SWITCH POS. AFTER WE PARKED; WE CALLED MAINT TO LOOK AT THE DISCREPANCY. WE THOUGHT THAT IT WAS ON PRIOR TO DEP; SO MAYBE THE VALVE DID NOT REMAIN WIRED OPEN. MAINT LOOKED AT THE #1 ENG ANTI-ICE VALVE AND TOLD US THAT THE VALVE HAD NOT BEEN LOCKED IN THE OPEN POS AS PER THE MEL (30-11). THEY COMPLETED THE PROC AND WE VERIFIED THE VALVE POS BY STARTING THE #1 ENG. WE THEN DEPARTED NORMALLY ON OUR NEXT FLT WITH THE SAME ACFT.
