check the presure regulation valve after you are sure that isnt damaged from ice.

Try and back flush the washer..Take spay nozzle off washer and back flush with hose...If any kind of sand or deposits get into the Pump it will hold pressure valve open not letting it build pressure.after back flushing hook back up washer and before you put spar nozzle back on or start washer turn water on and make sure all air is out of washer..hook spray nozzle back up and hold it open with washer still off.when you see that there is no more air coming out of washer start it and you should have pressure.Hope this helps you and have a great day!!
