Hi Prudie x
What brand and make? This is likely to be ..
1st: No water at hose inlet (if connected with one of those easy plumb piercing connectors, it is suspect) Check hose supply with bucket (hoping you can operate tap ok)
2nd: Water inlet solenoid failed. (If you have water available, and you can hear a faint humming, or nothing happens) This will need stripdown of rear/top panel to gain access.
3rd: Failed timer unit/elec control panel. Not normally worth fixing, even on expensive brands.
