Swamped with a load of laundry (5)
I believe the answer is:
awash
'swamped' is the definition.
(I've seen this in another clue)
'with a load of laundry' is the wordplay.
'with' says to put letters next to each other.
'load of laundry' becomes 'wash' (I've seen this in another clue).
'a' next to 'wash' is 'AWASH'.
(Other definitions for awash that I've seen before include "Flooded with water" , "Drenched" , "Covered by water - sounds cleansing" , "becomes flooded" , "Swimming" .)
