- Stainless Steel Tub with third rack
The Frigidaire FDSP4501AS is a current 24-inch built-in dishwasher. This top-control, fully-integrated model adds a stainless tub, a third rack, the BladeSpray Arm, and EvenDry for quieter, drier loads.

The codes worth knowing on the FDSP4501AS number about five. i20 and i40 are a drain or fill restriction, also displayed as iF0 and identical in cause; i30 is a float or leak trip; iC0 is a control communication fault; UO is the vent code. Our sequence is fixed — filter, drain path, inlet valve — and a genuine OEM part is fitted at the end of it, not the start. For the FDSP4501AS, see dishwasher repair and our dishwasher error-code guides. Full details on the FDSP4501AS, specifications and model lookup alike, are published at frigidaire.com, and our Frigidaire repair guides and model directory translate them into practical steps.
