I'm repairing a Samsung front-load washing machine and had to take the tub apart. The tub consists of two halves which are joined by a number of bolts and a thin (approximately 1/4) seal which appears to be made of EPDM (based on the label).
I'm installing a new seal and it appears there was no lubricant/grease used originally, and it's not mentioned anywhere in repair guides. However, I was taught that a gasket/seal isn't watertight without lubricant, and this being the most likely location for a leak I'm weighing the risk of applying a thin coat of silicone grease to the new seal.
Would that be a mistake as it's not to the manufacturer's spec? And would there be a risk of it causing problems now or in the future?
