water entering fridge vent

Perhaps keep the hose away from them and do that bit with a brush and a bucket of water.

You can cover the vents or remove them. Usually this is done by sliding the small buttons inward and easing the vent out laterally [there is a small bit that slots into a groove on one end. If you were to remove them you could simply insert /stuff a rag or similar into the opening to absorb any water whilst washing. Clean the vents whilst out and refit. Read the user manual if you are unsure on how to remove and refit.

When washing that area, always have the hose directed downwards so it is like rain and isn't forced into the vent. If rain doesn't get in, sensible washing won't cause water to go in either.

The obvious answer would be to remove the vent covers and wash them separately. However, this will not stop water from entering the fridge area when you drive on a very wet road. The spray which is generated would almost certainly get into the area, and there isn'y much you can do about it either. I guess that when you have the fridge on and some airflow gets going, it will eventually dry out.

Interesting topic fridge vents.Had a small warranty job done on some interior panelling on my van by a well known caravan repairer in Coff's Harbour and he told me to be very careful with all the external vents as they are the most likely origin of water ingression that has the potential to cause rot in the timber framework.I took on board what he said and have sealed most vents leaving only the critical ones open.Yes this will open up a can of worms on safety aspects I expect but I believe there is till sufficient ventilation remaining to be safe.Fridge vents of course have plenty of air and heat flowing through them to effect drying out of any dampness.

thanx for your responses. yes i'll just have to be a bit more careful in hosing down ( although this is more difficult for the top vent - use a ladder I guess.) I like the idea of taking out vents and replacing with another insert that seals (temporarily of course).
all replies are much appreciated
