Narrative:
IFR departure; climbing through 4000 feet MSL on a 040 heading the aircraft encountered IMC flight conditions & light snow. Light to moderate mixed ice began accumulating on the leading edges of both the left and right airfoils. Pneumatic de-ice boots were turned on and began their cycle. Center cleared the aircraft to 9000 feet MSL; direct ZZZ. Upon climbing through 8500 feet MSL the aircraft's central advisory and warning system (CAWS) reported an amber caption denoting a failure of our pneumatic de-ice boots. A visual inspection of the pneumatic boots cycle confirmed the CAWS indication. While in icing conditions both pilots were in agreement to contact center; request priority handling; in an attempt to exit icing conditions and divert the aircraft to ZZZ1. Center cleared the aircraft down to 6000 feet MSL; direct ZZZ1. While in the descend to 6000 feet MSL the moderate icing conditions continued. [Center was notified and acknowledged my diversion] request; notified approach; and instructed the radio handoff. Approach cleared the aircraft down to an altitude which was VMC. Within 10nm of ZZZ1 both pilots confirmed the airport in sight and advised approach. Approach cleared the aircraft for the visual approach to runway xx. The crew executed a no flap landing as directed per the afm. ZZZ1 ground cleared the aircraft to parking. Upon engine shut down the crew informed all emergency personnel no further assistance was needed.
