hi,
'fishy' smell is typical of over heated plastic such as used for lampholders.
Remove dimmer & fit standard switch temp. until operation correct.
You are missing a black wire!
there should be 2 blacks on one side connected to the blue of the flex, plus one on other end which should be sleeved red as it is the switch return line and is live not Neutral, & should connect to the brown flex.
Recheck wiring and check for loose connections.
Lamp holder pins may be sticky and not making good contact with lamp contacts,
regards Sparx
