A dishwasher drain pump is the same part whether it is behind a cabinet panel or not. What differs is the hour spent getting the panel off and back on square. The same is true the other way: refrigeration sealed-system work costs what it costs because it is built-in refrigeration, and that is physics rather than a premium on the name.
So the figures on these pages follow the work rather than the make. Where a job is genuinely cheap on this equipment — the hood, the filter reset, most induction call-outs — the page says so.
