Default Suppression caps on sewing machine motors - needed?

Got a nice metal bodied sewing machine electric motor 230v 5Amp 30 watt model (think it's Sew brand) to use with a minature lathe milling head (Emco Unimat 3 part) I have. Connected it all up to the mains for a tryout and everything was fine except one of the mains suppression caps went bang with a vengence - ruptured and brown goo everywhere.

How essential are these to supress rf Tempted to not bother replacing it as the motor will be only used in my shed and on a isolating transformer supply.
