(1) Usange kulumikizgana kwa vavu ya solenoid kuli kufwatuka panji kukuwa, ndipo vavu ya solenoid yikukhozgeka yayi, connector yingaŵa yakukhozgeka.
(2) Coil ya vavu ya solenoid yikuwotcheka. Waya wa solenoid wangafumiskikapo na kupimika na multimeter. Usange dera lajulika, coil ya solenoid yizamuwotcha.
Vifukwa ni coil ya damp, kuvikilira makora yayi na kudontha kwa maginito, ivyo vikupangiska kuti coil yiŵe yakujumphizga na kuwotcha. Valve ya solenoid njakudura, ntheura nchakukhumbikwa kuti maji gha vula ghaleke kunjira mu valve ya solenoid. Kusazgirapo apa, usange nyengo ya vula njakusuzga comene, nkhongono yakucitira vinthu njakukwana comene, chiŵelengero ca matengo gha coil ngacoko comene, ndipo nkhongono yakuyamwira njakukwana yayi, coil yizamuwotcha.
