No you should not wash fruit or vegetables using dish soap or any other soap.
If you wash fruit or vegetables with dish soap or any other soap you might leave some soap residue on the fruits or vegetables which can cause a bad taste to them.
The fruit and vegetables may also absorb some of the soap and then the soap would be in the fruits or vegetables and then it would taste awful.
You can clean vegetables and fruits using some vinegar which should easily clean and even disinfect the fruits and vegetables without leaving any bad taste to them.
Mix some vinegar and water together and then wash them off that way.
Or add some vinegar and water to a bowl and soak your fruits and vegetables in that and your fruits and vegetables should be clean and there will not be any soap residue on them.
