How can I tell what size my dishwasher is?
For your GE GLD5500L00BB dishwasher, you can tell the “size” by measuring the cabinet opening and comparing it to standard built-in dishwasher dimensions. Most built-in dishwashers fit a 24-inch-wide opening; the installation specs for this model call for a 24-inch minimum width and 24-inch minimum depth opening.
Use a measuring tape and measure the opening, not the dishwasher door.
- Width: cabinet to cabinet at the front of the opening
- Height: floor to the underside of the countertop
- Depth: front of cabinet opening to the back wall
- Corner clearance: if installed in a corner, allow 2 inches minimum to the adjacent cabinet or wall
- Door swing clearance: allow about 28-3/8 inches minimum in front for the door to open
For the exact installation requirements and diagrams, use the installation guide.
Here is a quick comparison to help you interpret your measurements.
| Measurement | Typical built-in dishwasher | GLD5500L00BB install opening target |
|---|---|---|
| Width | 24 in. | 24 in. minimum |
| Depth | 24 in. | 24 in. minimum |
| Height | ~34 to 35 in. | ~34-1/2 in. (floor to underside of countertop) |
Correct sizing prevents installation problems like the dishwasher not sliding in fully, the door rubbing cabinets, or the unit sitting out of level. It also helps when ordering installation-related items (for example, insulation or trim) and planning clearances.
- Measure in multiple spots (front and back); cabinets are not always perfectly square.
- Confirm the floor is even in the opening; an uneven floor changes effective height.
- If you are replacing an older unit, measure the opening even if the old dishwasher “fit fine.”

How old is my GE GLD5500L00BB dishwasher?
Your GE GLD5500L00BB dishwasher’s age is determined by its serial number, not the model number. Find the serial number on the tub wall just inside the door, then decode the first two letters to identify the month and year of manufacture (that date tells you how old the dishwasher is).
Look for the model and serial tag:
- On the tub wall
- Just inside the door opening
- On the rating label that lists Model # and Serial #
For the exact label location and diagrams, use the owner's manual.
On GE dishwashers, the serial number format uses letters and numbers; the key detail is:
- The first two letters of the serial number indicate the manufacture month and year
- The remaining characters identify production sequence
- Write down the full serial number exactly as shown
- Use the first letter for the month code
- Use the second letter for the year code
- Convert those codes to a calendar month and year
“Age” is typically counted from the manufacture date, not the purchase date. If you still have your receipt, you can compare both.
| What you have | What it tells you | Best use |
|---|---|---|
| Serial number | Manufacture month and year | Determining appliance age |
| Receipt/closing docs | Purchase/installation date | Warranty timing and ownership records |
Knowing the manufacture date helps us match the right GE dishwasher parts and troubleshoot common issues by era, especially for items like the control board, door switch, and pump components.

What is a GLD5500L00BB code?
GLD5500L00BB is not an error code; it is the GE dishwasher model number. We use it to match the correct parts, wiring, and control-panel features for your specific dishwasher, and to pull the right troubleshooting steps from the owner's manual.
On GE dishwashers like GLD5500L00BB, the model and serial tag is typically located on the tub wall just inside the door.
- Open the door and look along the inner tub wall near the door opening
- Write down both the model number and serial number
- Use the full model number (including all letters and numbers)
- Match the model number exactly when ordering parts
This model family uses status indicator lights and may flash to indicate a malfunction. If you are seeing blinking lights or a pattern on the control panel, use the troubleshooting and control-panel sections in the owner's manual to interpret what the dishwasher is reporting.
- Door not fully latched (door switch not closing)
- Control not “booted” after power was turned on (wait 5 to 10 seconds before pressing Start)
- Cycle not started within the allowed time after closing the door
- Power interruption that reset cycle options
| What you see | What it usually means | What to do next |
|---|---|---|
| CLEAN light on | Cycle completed | Open door to clear reminder or select a new cycle |
| Lights flashing during operation | Possible malfunction indication | Check troubleshooting section for the specific pattern |
| No response to Start | Door latch or control issue | Confirm door closes firmly; then review start/reset steps |
Using the correct model number prevents ordering the wrong GE dishwasher parts (for example, a control board or door switch that looks similar but does not fit). It also ensures the troubleshooting steps match your exact control-panel style.

What is the most common problem with a GE dishwasher?
For the GE GLD5500L00BB dishwasher, the most common issues we see are won’t start, won’t drain, or doesn’t clean well. Many of these come down to basics like a door that is not fully latched, a canceled cycle (START/RESET), low water temperature, or a clogged drain path. See the owner's manual for model-specific troubleshooting steps.
- Make sure the door is fully closed and latched; the dishwasher will beep if the door is left open during operation.
- If the START/RESET light is flashing, let the unit drain (about 90 seconds) after canceling or restarting a cycle.
- Confirm hot water is reaching the dishwasher; we target 120°F to 140°F at the sink before starting a cycle.
- Check loading: dishes should not block the detergent cup or spray arms.
- Use only dishwasher detergent (not hand soap); the wrong detergent can cause suds and poor washing.
| Symptom | Most likely cause | What to do next |
|---|---|---|
| Won’t start or stops | Door not latched, cycle canceled | Re-latch door; press START correctly; avoid opening mid-cycle |
| Won’t drain | Clogged air gap/disposer, drain restriction | Clean the air gap; check disposer inlet; verify proper drain loop |
| Dishes not clean | Low water temp, blocked spray arms, poor loading | Run hot water first; reload; inspect spray arm movement |
| Spots/film | Hard water, low rinse aid, too little detergent | Use rinse aid; adjust detergent; follow manual’s vinegar cleaning method |
If troubleshooting points to a failed component, these model-matched parts are common suspects:
- Dishwasher door switch WD21X10224 (won’t start when the door is shut)
- Dishwasher drain pump WD26X22719 (won’t drain or drains slowly)
- Dishwasher filter WD12X10109 (poor cleaning from restricted wash water flow)
- Dishwasher spray arm WD22X10047 (poor cleaning from weak or uneven spray)
Start, drain, and cleaning complaints often share the same root causes: the dishwasher must sense a closed door, fill with properly heated water, and circulate water freely through the filter and spray arms. Fixing the underlying cause prevents repeat cycle failures and improves wash results.
