1, kebera oba waya z’amasannyalaze ziri ku:
Kebera ebiyungo era okuyungibwa kwayo okwa waya kukolebwako amaanyi ne vvulovumenti y’okugaba, ekifo ekitereezeddwa okutuuka ku kifo ekya bulijjo oba nga kiwunyiriza, coil to coil short circuit welding, replacement coil work differential pressure is not appropriate, differential pressure, fluid temperature is too high, replace solenoid valve commenutive change of main dead valves. Singa ekisiba kyonoonebwa, zzaawo ekisiba oteekemu ekyuma ekisengejja.
2, vvaalu ya solenoid tesobola kuggalwa nga ku mulimu:
Kikyuseemu ekisiba Singa omusingi gwa vvaalu enkulu oba omusingi gw’ekyuma ogutambula nga gwonoonese, oba ebbugumu ly’amazzi n’obuzito (viscosity) biba waggulu nnyo, okukyusa obucaafu bwa vvaalu ya solenoid bibeera valve core production imperities mu solenoid valve oba moving iron core, okuyonja, ensulo ebadde ku oba deformation, obulamu bwetaaga okukyusibwa, orifice balance blockage, okuyonja mu budde, okukola frequency nnyo oba okubeera n’obulamu oba okubeera n’obulamu oba okukola oba okutereeza ebintu.
