Most machines don't even have one anymore because of the noise they made in pump outs. That Frgidaire looks simple, but also cheaply designed. At least it was able to be fixed. |

How many chopper blades do the frigidaires have? What are they made of? |

I like my dishwashers to have quality chopper blades in them. My whirlpool point voyager has 2 stainless steel blades in the food grinder so tough food particles get pulverized. It does matter. I am about quality, not quantity. |

Induction motors are significantly better then brush motors. Yes a very poor induction motor might fail before a good brush motor, but in my experience GE has some of the best motors for any modern dishwasher. The redesigned motors from 2000 are still chugging along. Comparing a brush motor to a GE quiet power motor is imo a no brainier.
If Frigidaire is still using brush motor on their DW I do not think that looks good in terms of reliability. |

Well you'll be crying in your Cheerios to hear that GE and Elux now source their little brush motors from Johnson Elrctric. A Chinese firm with an English name.
They're AC fed, but have a built in AC/DC converter and permanent magnets. All make the same distinctive brush 'whine'. Though they seem pretty powerful thus far. |

A motor is as good as its bearings, rare earth induction magnets, or armature windings and carbon brushes. On a copper wound motor, all it takes is one broken spot to cause failure. |

Chet, you're 100% correct.
The very low end standard tub GE machines still use the now "old" (aprox. 1/8hp) induction "quiet" motor. I believe they're now made in China and Vietnam. Sadly....they used to be made in the USA and Germany back in the 'good old days.' They're still a great motor though. Probably my favorite. |

SR motors need a microprocessor to control the sine waves. |

What types of wash pumps do the frigidaires use from the BOL to the TOL models? |

I noticed that the BOL model frigidaires have a single speed pump while the TOL models have a variable speed pump. Why is that? |

It looks like you guys are right. I found this thread with a new GE dishwasher (congrats btw :) ) and the motor looks identical to Frigidaire's.

This place is bar none. :) Really eye opening.
As for variable speed pumps... one theory I have might be low water ususage. Some ultra high end machines from the past would actually cycle the motor every couple of seconds. The sump would fill, the motor would rev up sending water to the arms and then it would coast down for water to re-enter the sump. When it did it would rev back up again. If the motor rain continuously 2/3 of the time it would be pulling in air. Frigidaire, at least their low end models over come this by using a diverter so only one wash arm can run at a time. |
